Stephane Le Foll, the French Socialist government's spokesman and its agriculture minister, said on Tuesday he backs his party's official candidate Benoit Hamon but might vote for independent centrist Emmanuel Macron instead.
Left-wing outsider Benoit Hamon will fight former prime minister Manuel Valls for the French Socialist presidential nomination on Sunday after winning the first round of the party's primary.
Former French Prime Minister Manuel Valls called on Monday for a big turnout in the second round of the Socialist primaries after a first round vote made left-wing rival Benoit Hamon frontrunner to represent the party in this year's presidential election.
