What happens after France's first election round?

23 April 2012 Last updated at 10:31 BST

French President Nicolas Sarkozy faces an uphill struggle in the second round of the presidential election, after coming second in Sunday's first vote.

He won 27.1% of the vote, while his Socialist rival Francois Hollande took 28.6%, the first time a sitting president has lost in the first round.

The two men will face each other in a second round of voting on 6 May.

Third-place Marine Le Pen took the largest share of the vote her far-right National Front has ever won, with 18%.

Julien Chevignon, of pollster YouGov France, told the BBC's Katya Adler in Paris that what happens next depends on where the non-Sarkozy and Hollande voters go.
