Ukip are expected to win the European Parliament elections in the UK – narrowly leading the Labour Party in the latest poll.
The YouGov survey has Nigel Farage’s party one point ahead of Labour, while the Conservatives are expected to come in third place for the first time at a national election. The Green Party are predicted to finish ahead of the Liberal Democrats in fourth place.
Polls are open in the UK until 10pm tonight, while some countries across Europe will vote up until Sunday – when results will be announced.
The make-up of the European Parliament is not expected to significantly change.
Currently, the European People’s Party (EPP) is the biggest political group in the European Parliament - with 274 MEPs, ahead of the Progressive Alliance of Socialists and Democrats (195) and the Alliance of Liberals and Democrats for Europe (85).
Since the parliament was set up in 1979, the turnout at elections has gradually dropped. The last elections were held in 2009 - where 43 per cent cast their vote.
Polls have indicated that anti-EU or protest parties are expected to increase their share of the seats from 25 per cent to 31 per cent. However, a coalition of the EPP and the Socialists is expected to control more than 420 out of the 751 seats.
