US pharmaceutical shares have fallen after Democratic presidential candidate Hillary Clinton and the White House weighed into the controversy over the pricing of Mylan's Epipen.
Mylan sank by more than 5% as Clinton and the White House criticised the drugmaker for raising the price of epinephrine injectors from $100 to $500 over five years. The injectors are used to counter life-threatening allergic reactions.
Fellow biotech and pharma companies Amgen, Biogen and Celgene all lost at least 2%, while the Dow members Pfizer and Merck also fell.
Portugal has agreed a deal with the European Commission which will help to recapitalise the ailing state-owned bank CGD. The agreement would see over €5bn injected through a mix of state funds and money raised from the markets.
Caixa Geral de Depositos, Portugal's largest bank by assets, needs to bolster its capital because of massive bad loans on its books.
"This is an innovative deal in Europe," Finance Minister Mario Centeno said. "This is good news not only for CGD but for the whole Portuguese banking system."
Portugal's government has been negotiating with Brussels for months so the injection doesn't fall foul of strict EU rules and doesn't count towards the deficit.
The Financial Times leads with the US Treasury's intervention on the tax probes by the European Commission into Apple and other American multinationals.
Government plans to sell off Holloway Prison - the biggest women's prison in western Europe - have moved a step closer after a property agent was appointed.
The Ministry of Justice has picked Billfinger GVA to advise on the sale of the 164 year-old jail in north London. The last prisoners in Holloway - which in the past housed members of the suffragettes and Myra Hindley - were moved in June.
The government is still in the early stages of considering how the land will be used and no decisions have yet been made. Holloway was marked for closure last year after being branded "inadequate" by inspectors.
UK households spent more on drinking and eating out in July, despite uncertainty about the economic impact of the Brexit vote, according to a survey by pub chain Greene King.
On average, householders spent £47.18 on drinking out - a 7% increase on a year ago - and £91.35 on eating out - an 8% increase.
That was despite one in three respondents to the survey saying they expect their financial situation to be worse off this time next year.
"The impact of Brexit on personal finances is a concern but, in fact, UK adults are more pessimistic about the prospects of the wider economy and the potential threat of recession later this year," said Rob Rees, Greene King marketing director.
South Africa's finance minister has said he will not appear before police despite a request to do so. Pravin Gordhan says allegations against him related to his time as head of South Africa's tax agency are wholly unfounded.
Mr Gordhan says his legal team has advised him he is under no obligation to go to the police. South Africa's currency, the rand, had earlier fallen amid the problems facing the finance minister at a time when the country teeters close to a recession.
Oil prices have tumbled after a surprise jump in US crude stockpiles added to concerns about global oversupply.
The US Energy Information Administration (EIA) reported that crude inventories rose 2.5 million barrels last week, compared with analysts' forecasts for a drop of hundreds of thousands of barrels.
A French naval contractor said it may have been the victim of "economic warfare" after secrets about its Scorpene submarines being built in India were leaked.
India and France have ordered investigations into the massive leak, which exposed details about the combat capability of the vessels being built by DCNS in Mumbai.
According to The Australian newspaper, over 22,000 pages of documents reveal, for instance, the Scorpene's diving depths, range and endurance.
France's DCNS said it was working to determine if any harm had been caused to clients with a view to drawing up an action plan.
Asked if the leak could affect other contracts, a company spokeswoman said corporate espionage could be to blame, Reuters reported.
"Competition is getting tougher and tougher, and all means can be used in this context," she said. "There is India, Australia and other prospects, and other countries could raise legitimate questions over DCNS. It's part of the tools in economic warfare."
If you enjoy a refreshment at the 19th hole then you are no doubt an aficionado of the sport of golf.
Golf has enjoyed a successful return to the recently-completed Olympic Games in Rio.
But it came against a backdrop of two of the world's biggest sports equipment and wear producers, Adidas and Nike, looking to sell the majority of their golf businesses.
BBC business reporter Bill Wilson looks at the reasoning behind the sell-off plans.
The US Treasury has clashed with the European Commission about taking action against Apple and other American firms over tax avoidance allegations.
The US regulator accused Brussels of acting like a "supra-national tax authority".
The commission is investigating a tax deal Apple was granted for setting up headquarters in Ireland. It could result in a billion pound tax bill for Apple.
In response, the commission said it noted the Treasury's report and added: "All companies, no matter their nationality, generating and recording their profits in an EU country should pay taxes in line with national tax laws."
Google is to penalise websites that feature intrusive pop-up adverts. It is updating the algorithms used to rank its search results so that offending pages are more likely to get lower placings.
Google makes much of its money from placing ads on the mobile web. One expert said the company wanted to give users one less reason to use ad-blockers or search within apps instead.
For its part, Google said the move should make using some of its results less frustrating.
The change is due to come into effect on 10 January.
Gold bullion finished trading this afternoon almost 1% lower at about $1,326.79 an ounce.
The drop prompted gold miners Randgold Resources and Fresnillo to fall on the FTSE 100 - by 5% and 4% respectively - and Acacia Mining to end the day as the biggest faller on the FTSE 250.
The yellow metal has climbed more than 20% this year amid global uncertainty and record-low interest rates.
... there's an award for Banknote of the Year? Well, luckily there is, and England's new plastic five pound note - featuring Winston Churchill - has been nominated.
The fiver - which will enter circulation next month - is up against the Maldives' 1,000 Rufiyaa note, Switzerland's 50 franc note, New Zealand's 50 dollar note and Georgia's 50 Lari note. Scotland's new five pound note - also plastic - is the other nominee.
Banknote enthusiasts can see the nominations here. My favourite is the Maldives' offering, which features a turtle and a whale. Not very patriotic of me, I know...
Easyjet has confirmed that a flight from London to Belfast returned to the stand to replace two crew members following a "verbal disagreement between them".
"The safety and welfare of our passengers and crew is easyJet’s highest priority and in order to deliver this easyJet’s cabin crew need to be able to work as a team," the company said.
“We would like to apologise for any inconvenience caused by the resulting delay. The flight has now continued to Belfast.”
The FTSE 100 has fallen back in the last couple of hours of trading to finish 0.5% lower at 6,835.78. The blue chip index was mainly pulled down by mining stocks.
Gold miner Randgold Resources was the biggest faller after the price of gold skidded 1%. A similar fate for copper prices sent Antofogasta and Anglo American down too.
The FTSE 250 of mid-cap UK firms, meanwhile, nudged 32 points higher to 18,014.65.
Britain's biggest supermarket is taking the fight to Amazon and Sainsbury's as it launches a same-day click and collect service.
Tesco customers can now order groceries online and collect them that day in nearly 300 stores. Orders need to be before 13:00 for a pick up after 16:00.
Supermarkets are no longer just competing on price but also time, as they seek to offer customers more convenience over when and how they do their shopping.
In June Amazon launched its assault by offering Prime members in London same-day deliveries on a range of fresh and frozen grocery items. Sainsbury's followed suit when it announced a trial of same-day grocery deliveries at three stores, rising to 30 shops by Christmas.
China has unveiled images of a probe and rover that it plans to send to Mars in 2020.
The plan is for a spacecraft to orbit Mars, make a landing, and deploy a solar-powered rover that will operate for three Martian months. "The challenges we face are unprecedented," said Zhang Rongqiao of the Mars mission, the State Council of the People's Republic of China reported.
After Sir Richard Branson's row with Jeremy Corbyn, the BBC has taken a look at why Britain's trains are so busy.
Richard Westcott explores the problem of overcrowding - and how track closures in the 1960s started it off - although if you've got a busy commute ahead of you in the 30C heat, you might prefer not to think about it...
It's doubtful that peace talks will end attacks on Nigeria's oil infrastructure, says Philip Walker of the Economist Intelligence Unit.
While the Niger Delta Avengers militant group has said it will observe a ceasefire, there are many more groups, most of which lack unified command structures, he said.
Plus, there's no unified political response to demands. The attacks have heavily disrupted Nigeria's oil supply, with about 200,000 barrels of crude oil a day stolen at their height.
PetroChina, the country's largest oil and gas producer, said the first half of 2016 has been the "most difficult period" for the company since it listed on the stock market nine years ago.
One of the largest oil firms in the world, PetroChina was hit by low oil prices, slowing demand growth in China and tougher competition from the country's independent oil refineries known as "teapots" .
The state-owned company said profit attributable to shareholders dropped to 531 million yuan (£60.2 million), from 25.4 billion yuan in the same period last year.
Based in Beijing, it is the listed arm of state-owned China National Petroleum Corporation (CNPC).
The world's longest aircraft - the Airlander 10 - is now back at its normal mooring location after nosediving on landing during its second test flight.
A statement from the company said: "Today the prototype Airlander 10 undertook its second test flight and flew for 100 minutes, completing all the planned tasks before returning to Cardington to land.
"The Airlander experienced a heavy landing and the front of the flight deck has sustained some damage which is currently being assessed. Both pilots and the ground crew are safe and well and the aircraft is secured and stable at its normal mooring location."
US stocks are little-changed in a listless opening few minutes of trading. Energy firms Exxon Mobil and Chevron have dipped slightly after a 1% fall in the oil price and ahead of a US oil inventory report out later.
For Czech locksmith Frantisek Hadrava, his 14-minute drive to work proved too arduous.
So he built a plane to fly himself to work instead. As you do.
Reuters reports that Mr Hadrava, a 45-year old locksmith from the south-western Czech village of Zdikov, took about two years of his spare time to build his ultralight plane.
It has an open cockpit, a propeller powered by a 3-cylinder engine made by Czech firm Verner, and a maximum speed of 146 km (91 miles) an hour. It cost about €3,700 (£3,100) to build, Mr Hadrava said.
He now lands on a meadow across the road from the factory ahead of his 6am start time. He pushes the plane across the road and parks it outside the factory.
"It takes me about 12-14 minutes by car," Hadrava said. "By plane, it would take around 4-5 minutes if I flew directly, but I take a bit of a detour so that I don't disturb people early in the morning. So it takes about 7 minutes."
On the currency markets, the pound is at a two-week high against the euro at more than €1.17. Against the dollar, sterling has risen above $1.32.
"A drop in UK mortgage approvals to a one-year low in July failed to dent sentiment towards sterling, with overall lending figures suggesting the Brexit vote has had little impact on consumers’ borrowing appetite," said Chris Saint of Hargreaves Lansdown.
The FTSE 100 has made back some of its losses from the start of the day, but is still 0.2% lower than Tuesday's closing price. It's currently at 6,853.09 points.
The biggest faller is Old Mutual, down 5%, followed by miners Glencore and Anglo American, down 4.7% and 3% each.
Advertising giant WPP continues to climb - it's nearly 6% higher now, after reporting a strong rise in sales for the first half of the year.

Why did Sir Richard Branson plunge into a row with Jeremy Corbyn - and why nearly a week after the incident?
Electric-car maker Tesla has said it has made the world's fastest production car. A new version of its Model S sedan can accelerate from 0 to 60 miles per hour in 2.5 seconds, the firm said.
Tesla chief executive Elon Musk said the company will offer a larger battery pack for versions of its Model S and X cars that will extend their range. For the Model S, that's beyond 300 miles.
Angry Birds maker Rovio has returned to profit. The Finnish mobile game maker said adjusted operating profit for the first six months was €5.7m, compared with a loss of €10m for the same period last year.
Revenue rose 16% to €76.4m on the back of higher game sales. The figures do not include profits from its Angry birds movie, which has reaped about $350m at the box office worldwide since its release in May.
Rovio plans a sequel to the first film, which the privately owned company financed itself.
The "challenger" bank said it had increased its focus on professional landlords and tightened lending criteria for smaller residential developments in the wake of the Brexit vote.
While saying it was not directly exposed to the EU, OneSavings admitted that an economic downturn could affect its business by reducing demand for mortgages if the housing market slows down.
