Tories and Labour braced for Europe poll backlash
Both the Conservatives and Labour are braced for a backlash from voters over Brexit as the results of the European elections are announced.
Opinion polls have suggested Nigel Farage's Brexit Party could be on course for victory in the European contests, with results due to start coming in on Sunday night.
However, European elections traditionally see low turnouts and many voters may have decided to stay at home. That could mean as little as 17-20%, may have backed Mr Farage's no deal movement. The turnout figures will be widely watched for an indication of just how popular the Brexit Party has become.
The Liberal Democrats, from the opposite side of the Brexit divide, are also expected to pick up votes.
The European elections took place almost three years after the UK voted to leave the EU because of Theresa May's failure to get her Brexit deal through Parliament, and could deliver a damaging blow for the Tories after a distinctly lacklustre campaign.
Prominent Conservative MEP Daniel Hannan said he feared the party was facing "total wipeout" and would be left without any representation at all.
The Brexiteer, who has been a member for South East England since 1999, said he suspected the party would be left with "zero MEPs" following the poll.
Seventy-three MEPs will be elected to represent the UK, with England, Scotland and Wales using a form of proportional representation called the D'Hondt system and Northern Ireland using the single transferable vote method.
Mr Farage, who is standing in the South East constituency, said: "If you want Brexit, you've got to vote Brexit. We did it once, they ignored us, so we're going to tell them again."
In a polling day video message, Mr Corbyn warned "the far right is on the rise" and Britain was "at a crossroads".
"The actions we take now will have huge consequences for our future," he said.
On a campaign visit to Worthing, he added: "This Government can't last very long. And so, get ready for a general election."
But in a sign of Labour's divisions over Brexit, pro-EU MPs Wes Streeting and Ben Bradshaw both spoke of difficult doorstep experiences.
Former Cabinet minister Mr Bradshaw said it was a "dispiriting" experience to see Labour voters "flocking" to the Remain-supporting Greens and Lib Dems, while Mr Streeting said it was "not the easiest of polling days".
Writing in The Observer, deputy Labour leader Tom Watson said the party was "braced with a sense of despair" and blamed Labour's ambiguous position on a second Brexit referendum for losing votes.
"I want reports of high turnout in Remain areas to reflect a huge gain in votes for Labour. I fear that won't be the case," he said.
In Ireland, an exit poll has indicated the Green Party could top the European election in Dublin.
The increased support looks widespread, even accounting for a 4% margin of error, and could see an unexpected boost in Ireland's two other constituencies, RTE said after commissioning a RedC exit poll.
