Candidates vying for the EU's top job - president of the European Commission - have been canvassing support across the 28 member states.

Four men and one woman are standing, in the hope that success for their respective party blocs in the European elections will bolster their chances.

The four-day elections end on Sunday, when most EU states vote.

Luxembourg's Jean-Claude Juncker, of the centre-right, and German socialist Martin Schulz are favourites.

Belgium's Guy Verhofstadt is standing for the liberals, Germany's Ska Keller for the Greens and Greece's Alexis Tsipras for the radical left.

The idea, as promoted by the European Parliament, is that the party which gets the most seats in the elections wins the prize of selecting the EU's chief executive.

However, he or she will also have to be approved by EU heads of governments.

In Britain, for example, the main coalition party, the Conservatives, has not endorsed any of the five candidates.
