Nigel Farage's Brexit Party is set to sweep to victory in the European election, with Theresa May's Conservatives trailing and due to win around 10 per cent of the vote, according to a BBC projection.
The Liberal Democrats, from the opposite side of the Brexit divide, are.
The vote only took place because of the delays to Brexit, which should have taken the United Kingdom out of the European Union before polling day. May's ruling Conservatives were forecast to get between 10 and 12 per cent of the vote.
With results in from the first five regions, there was no question that the newly formed party was the victor, polling around 31.6%.
Britain was supposed to have left the European Union on March 29 but the entire process has been held up by a parliamentary deadlock. That is now scheduled for October 31.
The MEPs elected from the South East region are: Nigel Farage, Alexandra Phillips, Robert Rowland and Belinda De Camborne Lucy for the Brexit Party; Catherine Bearder, Anthony Hook and Judith Bunting, Liberal Democrats; Alexandra Phillips, Green; Daniel Hannan, Conservative; John Howarth, Labour.
The Brexit Party's popularity surge hastened her demise, with May announcing she will step down on June 7. Labour came third in Wales. The Conservatives were beaten into fifth place.
Pro-Europeans fear Brexit will make them poorer, undermine London's position as a global financial capital and weaken the West as it grapples with Donald Trump's unpredictable US presidency and growing assertiveness from Russian Federation and China.
The loss of Britain for the EU is the biggest blow yet to more than 60 years of efforts to forge European unity after two world wars, though the 27 other members of the bloc have shown surprising unity during the tortuous negotiations.
"It looks like it's going to be a big win for the Brexit Party", Farage told reporters as he arrived in Southampton for a vote count for the South East region where he is standing as a candidate.
