Wondering what's been happening on the campaign trail, three days before the general election? Here's a round-up of today's activities so far...

• Following a brief pause in campaigning following Saturday night's terror attack on London Bridge, Jeremy Corbyn has said Theresa May should pay a price at the election for ignoring "repeated warnings" not to cut police numbers
• The Labour leader said Mrs May had "presided" over a 19,000 fall in numbers as home secretary and he agreed with those calling on her to resign in the wake of the London Bridge attacks
• But the prime minister said she had protected counter-terror police number - and accused Mr Corbyn of opposing shoot-to-kill policies
• Plaid Cymru's leader Leanne Wood said Mrs May should take responsibility if Britain has been too soft on extremists

Answering journalists' questions, Theresa May says "now is not the time" for a second Scottish independence referendum.

During her speech, she said she was a "passionate" supporter of the Union.

Before that, Scottish Conservative leader Ruth Davidson urged voters to send a message to SNP leader Nicola Sturgeon:

BBC political correspondent Ben Wright says Theresa May is trying to impress on voters and Conservative supporters that this election is not in the bag - that a loss of six seats would lose the party its majority.

He comments that this is the PM's third visit to Scotland since the election was called, which demonstrates the Conservatives' ambition to reverse the decline of the party in Scotland.

Ben says Mrs May has put terrorism, along with Brexit, at the heart of her campaign, although she is being dogged by questions about her record as home secretary on police numbers.

Theresa May is campaigning in Edinburgh, telling supporters: "We are four proud nations but one united people."

She returns to her core campaign theme of "strong and stable leadership" and who is best qualified to lead Brexit negotiations which, she adds, start 11 days after the election.

She says the alternative to her as prime minister is "Jeremy Corbyn in Number 10 and Nicola Sturgeon pulling the strings from Bute House".

Mrs May adds: "Give me the authority to speak for Britain."

Polls show the gap between the Conservatives and Labour has closed dramatically during the course of the election, but how reliable are they? Chris Morris reports.

Security minister Ben Wallace has told the World at One that five terrorist plots had been stopped in the past two months and many more in the year as a whole.

Defending the government over accusations that the terror threat was exacerbated by the overall level of cuts in police numbers - some 19,000 since 2010 and a fall in the number of armed officers - Mr Wallace said: 'We haven't cut the counter-terrorism budget and let's not forget in all this that crime is down 30%.

"Our security services and police have had a tremendous success in a number of plots. They've disrupted 5 plots alone since the Westminster Bridge attack and indeed 18 over the last year. That's a significant number. There are many, many other plots - dozens - that don't make it to sophistication because we have either disrupted them or made sure they don't progress."

Lord Owen, who was once a Labour foreign secretary but went on to lead the SDP, says the country needs to "strengthen our mechanism" for responding to reports from the public about terrorism.

Lord Owen, who is now an independent, crossbench peer, tells the World at One: "If you do fight wars outside your own country, you get identified by the people who live in those countries either positively or negatively."

This means you "make enemies", he argues - but he insists that the UK only fights wars when it has to.

"I bow to no-one in my admiration of what the security services try to do," says former Labour Foreign Secretary Dame Margaret Beckett, who has also served on Parliament's Intelligence and Security Committee.

She says the committee was "concerned" when control orders were dropped and calls for all counter-terrorism measures to be looked at "afresh".

Dame Margaret adds: "I have a degree of respect for Theresa May but she cannot talk as though she's the only one with a degree of wisdom."

Shadow Cabinet Office minister Jon Trickett has said he thinks "everyone in the country" should listen to David Cameron's former policy chief Steve Hilton, who has publicly called for Theresa May to resign.

Mr Trickett said: "The former policy wonk in number 10 Downing Street who worked for the Conservative party has called for her resignation. And he did so because there are serious questions which need to be answered."

The World at One speaks to three former cabinet ministers following the London attack.

Lord Tebbit was a minister in Margaret Thatcher's cabinet, whose wife was seriously injured when the IRA bombed the Conservative Party conference in Brighton in 1984.

He thinks the timing of Saturday's attack has "more to do with Ramadan than our election date".

He praises the rapid response of the police on Saturday but thinks the security forces are "overwhelmed with third, fourth and fifth-rate intelligence" from some members of the public.

He likens it to intelligence gathering on the IRA, arguing that there were members of the public and people "in the highest ranks of politics on this side of the water who were extremely sympathetic to the IRA".

The number of police on our streets - armed or not - is now at the heart of an election row.

Michael Baker, UKIP's former candidate for the parliamentary seat of North Norfolk, says he'll be looking to get a colleague thrown out of the party for backing the Liberal Democrats' Norman Lamb.

UKIP's local government spokesman Peter Reeves, who is a Huntingdonshire councillor, issued a video urging voters to support Mr Lamb.

UKIP is not fielding a candidate in the seat - instead it had asked the 8,300 people who voted for them in 2015 to "lend" their votes to the Conservatives.

Mr Baker, who stood for the seat two years ago, says his immediate reaction to the video was one of "absolute incredulity".

He said: "I've known Pete Reeve for a long time and looking at the transcript of his endorsement video, I can only assume he's been working extremely hard on UKIP matters, the general election and his county council work and has probably overdone it and maybe is perhaps heading towards a breakdown."

He went on to say that he wondered whether it comes under the heading of fake news - "because we do know what people can do with cameras and video" - adding he hoped it was false news and that Norman Lamb wouldn't get tarnished by latching on to it and taking it as wholehearted encouragement to vote for him.

It might be the defining feature of politics in the social media age. So how can you pop your own "filter bubble"?
