Newspaper headlines: New Madeleine clues, Labour on Brexit and Ivanka in Berlin

Scotland Yard's revelation that they are following a significant line of inquiry in their investigation into the disappearance of Madeleine McCann makes the lead for the Daily Mail, Daily Express and Daily Mirror.

The Daily Mail says detectives believe it is the final throw of the dice to end a decade of heartbreak for her family.

Officers have not given further details but the paper says it is understood they have returned to the theory that burglars were involved.

The Daily Express says as the 10th anniversary of Madeleine's abduction approaches, police have held out hope she is still alive.

Brexit fog

Labour's Brexit policy, set out by Sir Keir Starmer, comes under the spotlight in many papers.

The Financial Times says the party failed to "clear the Brexit fog". While the Conservatives offer a clean Brexit and the Lib Dems a second referendum, it says, Labour's policy is complex and hedged.

The Daily Mail describes Sir Keir's stance as incoherent and self-contradictory, leaving the impression that Labour is in favour of both leaving the EU and remaining in it.

In the Sun's view, the shadow Brexit Secretary's strategy gives the EU licence to play hardball for years.

The Guardian says he declined to explain what would happen if the EU told Britain that the deal on offer in March 2019 was a "take it or leave it" one.

The Times wonders would he walk away or stay in. "The question was avoided," the paper adds.

Elsewhere, the Daily Telegraph quotes senior Whitehall sources as saying that Britain will have to continue paying into the EU budget after Brexit to secure a "transition" trade deal.

Where's Boris?

A number of papers report that some senior ministers are urging Theresa May to sideline Boris Johnson to little more than a cameo role in the election campaign.

According to the Times, one minister has suggested that the foreign secretary should be tied up in "lots of important meetings in various foreign capitals" between now and the election. Another said some of the Vote Leave pledges during the EU referendum makes Mr Johnson a liability at a time when the prime minister is seeking to reassure Remain voters.

But the Daily Mail says Mr Johnson has been assured he will be given a role in the campaign.

'Awkward foray'

The Times, Guardian and Daily Telegraph all feature Ivanka Trump on their front pages after the US president's daughter appeared at an international women's conference in Berlin, alongside the German Chancellor, Angela Merkel, and the head of the IMF, Christine Lagarde.

Describing her as the "First Daughter", they note the groans from some in the audience when she called her father a "tremendous champion of supporting families".

The Financial Times says it was an awkward first foray into global diplomacy and Ms Trump learnt the hard way about the pitfalls of diplomatic engagements.

A number of papers report that Twitter has stopped the police and security services from accessing data on potential terrorist threats.

According to the Daily Telegraph, the social media platform has withdrawn access to key streams of information which help them to identify plots, under plans to stop users' data being used for government "surveillance".

The Sun says Twitter sells the same information on messages its blocks to private companies.

Hummus crisis

According to the Times, weddings have become so lavish and elaborate that one of the country's leading observers of the middle classes has issued a plea for restraint.

Country Life magazine says there's been "the nuptial equivalent of an arms race" that has led to brides having three changes of outfit in one day and weddings captured for posterity not by the traditional photographer but a video camera attached to a drone overhead.

Mark Hedges, the magazine's editor, is quoted in the Daily Mail as saying: "Stop being competitive and start focusing on the magic of the romance."

Finally, several papers report on a shortage of hummus.

The Daily Telegraph says several supermarkets have stripped their shelves of the chickpea dip after customers complained about it having a strange, metallic taste.

It says many shoppers took to social media to vent their frustration.

The Times says the problem has been caused by a "production issue" at one the country's biggest suppliers.
