Eurosceptics and far-right parties have made significant gains across Europe in the European Parliament's election. (See here for UK and here for EU results).
In France the far-right party, the National Front, led by Marine Le Pen came out top with 25% of the votes across the country. The ruling Socialists party, led by President Francois Hollande, came in third with just 14%.
The National Front has campaigned for France to exit Europe and impose limits on immigration, including the reintroduction of border controls.
In the UK, the UK Independence Party (UKIP) swept through England, winning 25.7% of the votes and 23 MEPs.
Labour and Conservatives came in second and third, with just over one percent between them, whilst the Liberal Democrats saw significant losses, coming in fourth place after the Greens.

Labour 25.4%, 18 MEPs
Conservatives 23.94% 18 MEPs
Greens 7.87%, 3 MEPs
Liberal Democrats 6.87%, 1 MEP
Plaid Cymru 0.71%, 1 MEP
Scottish National Party (SNP) 2.44%, no MEPs
British National Party (BNP) 1.14%, no MEPs
Turnout was 34.19%. Northern Ireland is not included, as it has a different electoral system to the rest of the UK.
UKIP leader, Nigel Farage hailed the election win as "historic" and "extraordinary", whilst Prime Minister Cameron, said he "absolutely understood and received the message" from the electorate.
In Greece, exit polls predict a substantial win for the far-left, whilst the far-right Golden Dawn also made sizeable gains, coming in third.
Despite the gains of non-mainstream parties, the pro-European centre-right and centre-left bloc will continue to be the majority within the European parliament.
Election results predict a win for the centre-right European People's Party (EPP), set to win 212 of the 751 seats, reports Reuters.
"As the EPP has a strong lead ... I am ready to accept the mandate of the European Commission president," party leader, Jean Claude Juncker said. "We will have a clear pro-European majority in this house," he added.
The leader of the centre-left, Socialists, party and out-going European Parliament President Martin Schulz, said,
"It is a bad day for the European Union when a party with such a racist, xenophobic and anti-Semite program gets 24-25 percent of the vote in France."
"But these voters aren't extremists, they have lost trust, they have lost hope."
