Foreign Secretary Jeremy Hunt tweets: "Yes, we knew it was coming but still a painful result."

"Existential risk to our party unless we now come together and get Brexit done."

The SNP is on course to increase its number of MEPs from two to three in the European elections amid a collapse in support for Scottish Labour.

With 31 of the 32 Scottish council areas having declared their results, the SNP has 37.9% of the votes - up from 29% in the last EU election.

Nigel Farage's Brexit Party has the second-most votes and will have one MEP, as will the Lib Dems and Tories.

Labour is fifth with just 9.3% of the votes - down from 26% in 2014. It means Labour will lose both of its MEPs in Scotland.

The Western Isles will not declare its result until later on Monday, but it is unlikely to affect the overall Scottish result.

Newly-elected Brexit Party MEP Annunziata Rees-Mogg says she has no doubt her brother, Conservative MP Jacob, will be "devastated at what has been done to his own party".

She added: "Theresa May has betrayed the British people. She made a lot of promises she didn't stick to and unfortunately the whole party is paying for it."

Ms Rees-Mogg stood unsuccessfully as a Conservative candidate in the 2005 and 2010 general elections.

Change UK spokesman Chuka Umunna has defended the party's performance in its first election.

The newly-formed party has not won a seat in these elections and has gained more than 570,000 votes (3.4%) so far - with Scotland still to declare.

He told BBC Radio Four that the party's performance "can't be sniffed at".

"Of course we'd have liked to have done better and there was the odd misstep along the way."

"This is our worst-ever result," says Daniel Hannan, who has been re-elected as a Conservative MEP.

"We need to make Brexit happen, but in a way that will carry the 48% with us," he says.

He adds that his party now needs "different, credible leadership" to ensure Brexit is delivered.

Turnout in this election is running at just below 37%.

This is likely to be the second highest turnout in any EU election, second only to that in 2004, when the turnout was partly inflated by the use of all-postal ballots in some parts of England.

Turnout increased more in places that were most pro-Remain in 2016 compared to those places which voted most heavily for Leave.

In Remain areas the turnout was on average up by 5 points while in Leave areas it was up by just one point.

Change UK candidate and former BBC journalist Gavin Esler gives "huge thanks" to voters - after failing to win a seat in London.

"We have no desire to be dragged out of the EU against our will."

He says Labour and the Conservatives "got what they deserve" and specifically attacks Labour's "constructive ambiguity".

Labour's Jonathan Ashworth accepts that "our position hasn't worked" but adds "I don't think it is dishonourable to try and keep the two sides of the country together."
