The Lib Dems and the Green Party increased their vote share by 17.7% and 4.5% respectively.

Three parties saw their vote share fall - UKIP (29.9%) the Conservatives (20.7%) and Labour (7.4%).

The Brexit Party - who had not been formed at the time of the last election - won 37.8% of the vote share.

The Brexit Party leader Nigel Farage says: "There is a huge message here.

"Labour and Conservative Party could learn a big lesson tonight but I don’t suppose they actually will.

"We in the Brexit Party want to be part of the Brexit negotiation team.

"If we don't leave the EU on 31 October, tonight's results will be repeated in a general election."

The BBC is forecasting that British turnout is lower than the average - at about 37%. Earlier, the European Parliament said the Europe-wide turnout was around 51%.

Brexit Party: 915,686

Lib Dems: 653,743

Green: 343,249

Conservatives: 260,277

Labour: 184,678

Change UK: 105,832

UKIP: 56,487

Plaid Cyrmu leader Adam Price says the results show that "Wales is a Remain nation" and accuses Labour of "facing both ways".

"This is a historic victory for us - overtaking Labour for the first time in our 94 year history," he says.

"We need a people's vote to dislodge the parliamentary logjam."

The SNP campaigned on a very clear anti-Brexit message.

They specifically appealed to people who are not natural SNP supporters - people who are not necessarily in favour of Scottish independence.

The SNP told those voters 'lends us your vote to send a message.'

The Lib Dems have also done very well by doubling their vote from five years ago.

Labour have done very badly in these elections

That may be people who have voted Labour in the past 'lending' their vote to the SNP or the Liberal Democrats.

It is clear the SNP will be the ones celebrating tonight.

The 37% of the vote won by Brexit Party is five points above what UKIP achieved in 2014, much as in the rest of the country.

Meanwhile the Lib Dems have narrowly failed to overtake Lab on what is a 10% swing.

Here too the Greens have enjoyed a notable increase in support of 5 points while the Conservative vote has collapsed into fifth place with a 14 point drop in its support.

The Brexit Party - who did not exist at the time of the last European election - achieved a 38.2% share of the vote.

The Lib Dems and Greens grew their share of the vote by 11.8% and 4.5% respectively.

Three parties saw a drop in their share of the vote - UKIP (26%), the Conservatives (15.3%) and Labour (11%).

The turnout was 34.7% - a small increase on a turnout last time of 32.6%.

The Brexit Party chairman Richard Tice says: "People have backed us and the Labour vote is haemorrhaging.

"The reason it collapsed is because they haven't listened to their heartland voter, but listened to the mood in Islington instead."

In London, UKIP's vote share fell by 14.8% - meaning they lost their one London MEP who was also the party leader Gerard Batten.

Two grandees of the main UK parties have confirmed they backed the Liberal Democrats in these European elections.

Ex-Tory deputy prime minister Michael Heseltine has confirmed to BBC Radio 5Live that he voted Lib Dem, as he said he would before the polls opened.

While Labour's former director of communications Alastair Campbell said he hoped that his vote for the Lib Dems would help the Labour leadership "see sense".

The Brexit Party is up by 36.5% - and UKIP's vote share fell by 26.8%.

Labour and the Conservatives are down by 13% and 12% respectively.

The Lib Dems increased their vote share by 9.3% - the Greens by 5.1%.

Turnout in the area was 33% - pretty similar to the turnout in the last European elections in 2014.

Earlier in the evening Jeremy Corbyn's party lost in his own constituency.

Now, Theresa May experiences similar disappointing results in her area.

In Windsor and Maidenhead the Conservatives were beaten into third place by the Brexit Party who came first and the Lib Dems who came in second.
