For the second day running the political news has been dominated by tributes and further reaction to the death of Labour MP Jo Cox, 41, who died after being shot and stabbed outside her constituency surgery in West Yorkshire on Thursday.
Here is a round-up of today's events:
More than £150,000 has been raised for charities supported by murdered MP Jo Cox. Friends of the late Labour politician are raising money to support the three charities "closest to her heart" and chosen by her family following her death. They represent her campaigns as an MP to help civilians caught up in the Syrian war, to fight racism and extremism in Britain, and to help residents in her Batley and Spen constituency in West Yorkshire.
Politicians have been "inspired to rededicate" themselves to public service following the death of MP Jo Cox, Nicola Sturgeon has said.
Politicians across Scotland held their Friday surgeries as normal despite the death of the Labour MP, who was shot and stabbed after holding a constituency surgery in Birstall.
Ms Sturgeon paid tribute to Ms Cox at a meeting of the British-Irish Council.
Vigil events have been held in Edinburgh and Glasgow.
Conservative MEP Saj Karim has said he has had "very direct threats" made against him, as an MEP, which are currently being investigated by the police.
Speaking to the BBC's North West Tonight, he said: "There have been very direct threats which are now currently with the police, are being investigated and I anticipate that there are individuals who will be spoken to as a result of those threats."
He said there had been a building up of tensions as the political messaging in the EU referendum campaign had ratcheted up over the course of the last 10 days.
Mr Karim decided to step up security at his home in November 2010 but in the wake of the attack on Jo Cox MP, speaking about the level of security required for politicians, he said:
This has never been a part of our political culture here in the United Kingdom but at the same time neither has the use of very extremist, almost, political messaging ever been a part of it either and one of the things that I've seen is I've come across people who have simply been repeating those same sound bites that they've been hearing on the television and radio. It really has led to a situation now where campaigning has had to be suspended and people genuinely I think, are within their rights to feel quite intimidated by what has happened but this is a culture which is completely alien to British democracy."
Vigils have also been held in Glasgow and Edinburgh in memory of Jo Cox.
Addressing the crowd in George Square, Glasgow, Scottish Labour leader Kezia Dugdale paid tribute to someone she said was "the very definition of a moral crusade, wrapped up in humour and love".
A vigil is due to be held in Belfast at midday on Sunday outside the City Hall, the Labour Party in Northern Ireland said.
Former Labour leader Ed Miliband describes Jo Cox as "a fighter for justice" in all that she did, and someone who "showed no fear in the face of danger".
"We remember her too as somebody of the greatest warmth, generosity and compassion," he adds.
He says people should "honour her legacy" of giving "a voice to the voiceless" and "standing up against oppression where she found it".
Former acting Labour leader Harriet Harman follows, and says that although Jo Cox was "a passionately committed campaigner" for the causes of social justice, "she was never divisive".
Everyone must heed the words of her husband, who has said to "unite against the hate that killed her", Ms Harman adds.
She says that when political campaigning resumes, "we will still have our political arguments... but let's think about how Jo did her politics, let's aspire to leave behind the venom and the toxicity and the division".
That can be our best legacy to the wonderful, wonderful woman that was Jo Cox."
Beginning the speeches, Labour MP Wes Streeting says friendship and politics are two words "you don't often hear together" but he says they go "hand in hand" and are "more common" than people realise.
There is a particular bond of friendship that comes among a group of people elected to Parliament at the same time. For every MP, particularly every Labour MP, elected barely a year ago, the last 24 hours have felt as though we are drowning in tears for our friend Jo. We have suffered such a terrible loss."
He says the solidarity show in the wake of her death has been "overwhelming".
A two minutes' silence is being held in memory of 41-year-old Jo Cox MP and mother of two, who was killed on Thursday
As Big Ben tolls, the gathered crowd lower their heads in a moment of tribute and reflection.
Former Labour leader Ed Miliband, Harriet Harman and more of Jo Cox's colleagues are among the many in attendance.
Vigils have taken place across Wales in memory of the late Mrs Cox. About 300 people gathered in Swansea's Castle Square, to lay flowers, light candles and listen to speakers pay tribute to the 41-year-old.
Aberavon MP Stephen Kinnock, who shared an office with Mrs Cox, said Jo Cox stood for the things that are:
Best about our country: internationalism, compassion and the view that you solve problems by working with people - not against them. It made no difference to Jo whether you were a constituent with a problem or a Syrian refugee. We have lost someone who was a great force for good."
A vigil is being held at Parliament Square - opposite the Houses of Parliament - in remembrance of Jo Cox, who was killed on Thursday.
Former Labour leader Ed Miliband has laid flowers in memory of the late MP.
BBC political correspondent Chris Mason, who is at the scene, says politics is so often "an environment associated with noise" and yet tonight "it's just silence".
Former Labour shadow minister Caroline Flint says "it's still hard to absorb" what's happened to Jo Cox, and says her heart goes out to her husband, Brendan, and two children.
She describes the late MP as "a young woman who gave so much in her life" before she joined Parliament, and "she had so much more to give" as an MP.
"My memory of her... was this very positive person, funny, really committed to her work as an MP," she adds, and says: "She will be very, very sadly missed."
Speaking to Sky News, former acting Labour leader Harriet Harman says killed MP Jo Cox tried to achieve her objectives by "bringing people together" rather than by "creating divisions".
She adds that whatever the reasons behind Jo's "tragic" death, "let's take a moment to reflect on how we do our politics better".
And she says: "Let's not have anyone using politician as a dirty word," - adding that politicians are part of democracy and "we're there for the people".

The killing of Jo Cox will never be explained away.
It's stopped politics in its tracks today, different party leaders putting their differences aside to show respect.
And the referendum campaign where respect has been scarce is still on hold.
Insults and exaggerations are never far from political exchanges.
But the referendum campaign has included astonishingly harsh attacks on both sides, emotional appeals to our identity that go way beyond the usual.
BBC Radio 4
West Yorkshire Police has said it is working with the North East Counter Terrorism Unit as the probe into the killing of 41-year-old Jo Cox continues.
It said: "The suspect in custody has been medically examined by two specialist medical practitioners who have determined that he is both fit for detention and fit for interview and detectives will continue to question the suspect during the day."
The statement also said:
We are aware of the speculation within the media in respect of the suspect's link to mental health services and this is a clear line of enquiry which we are pursuing. We are also aware of the inference within the media of the suspect being linked to right wing extremism which is again a priority line of enquiry which will help us establish the motive for the attack on Jo. We are keeping an open mind and I do not wish to add to the speculation as we need to ensure that we conduct a professional investigation and do not compromise the need to bring the person responsible to justice."
Ed Miliband says Jo Cox's death shines a light on the way politics is conducted
The BBC understands that during the searches at Tom Mair’s house, detectives found Nazi regalia, including Nazi books and literature.
West Yorkshire Police said links to right-wing extremism and the suspect's mental health are lines of enquiry in their investigation into the death of Labour MP Jo Cox.
The phrase "out of touch political elite" trips too easily from certain commentariat keyboards.
It's a kind of all-purpose, good-for-all-occasions criticism of any politician. "They don't exactly replicate my views? Out of touch…."
But I wonder how many of the glib trotters-out of that phrase spend hours sitting in damp church halls or down-at-heel municipal offices, trying to deal with benefits problems, housing problems, issues with the NHS and the myriad of other questions people bring to their MPs.
Plenty of people have pointed out that the constituency surgery is a vital link between Parliament and People, rubbing the nose of our political leaders in the gritty realities of ordinary lives - but it is not the only one.
By any standard, today's MPs are both more independent and more active than previous generations.
But there's a side of an MP's life that they don't talk about very much; fear.
A man has been charged over an alleged abusive phone call made to the office of Labour former minister Ben Bradshaw.
The 37-year-old man will appear before magistrates in Exeter on 5 July accused of an offence under the Malicious Communications Act, Devon and Cornwall Police said.
It is alleged a message was left on an answerphone in the Parliamentary office of Mr Bradshaw, Labour MP for Exeter.
News of the incident emerged following the death of Mr Bradshaw's colleague Jo Cox, who died on Thursday after being shot and stabbed in the street outside her constituency advice surgery in West Yorkshire.
A Devon and Cornwall Police spokesman said:
An abusive phone call to MP Ben Bradshaw was recorded on his parliamentary office answering machine and heard on 15 June. The office informed Parliamentary Police, and Devon and Cornwall Police, which made an arrest on 16 June. A 37-year-old man from Exeter has been charged under the Malicious Communications Act 1988 with sending a communication of an offensive nature and bailed to appear before Exeter magistrates on 5 July."
Jo Cox's constituency Labour Party have paid tribute to the Batley and Spen MP, describing her as "a wonderful friend" who "meant the world to us".
A statement said:
She was a lovely woman who cared deeply about her family, her community and everyone around her. She had an incredible passion for helping people and trying to improve the world at every level, from making Batley station a nicer place for the people who use it, to championing the cause of the people of Syria who have suffered so much in recent years. She was intelligent, but so down to earth, and anyone who met her for the first time felt like they had known her for years. Above all, she was an amazing wife to Brendan and mum to her two children. It is a tragedy that they will have to grow up without their lovely mum."
The family of Labour MP Jo Cox has set up a fund for people to donate to three causes close to her heart.
A post on the gofundme page says: "In celebration and memory of Jo Cox, we are raising funds to support three charities closest to her heart, chosen by her family."
The fund hopes to raise £50,000 for charities, including the Royal Voluntary Service, which helps combat loneliness in Mrs Cox's Batley and Spen constituency; Hope not hate, which seeks to challenge and defeat hate and extremism within local communities, and The White Helmets volunteer search and rescue workers in Syria.
The web page features an image of Mrs Cox standing beside her house boat - the same photo her husband, Brendan, posted on Twitter shortly after she was attacked on Thursday.
EU referendum campaigning has been suspended nationally until Sunday, with less than a week before polling day, after the fatal attack on Labour MP Jo Cox.
The Remain and Leave groups, which have not campaigned since Thursday, have cancelled events planned on Saturday.
Meanwhile, Parliament, which was on a break for the referendum, will meet on Monday for tributes to Mrs Cox.
The mother-of-two died after being attacked in her constituency.
