Three days before round one of a French parliamentary election, President François Hollande's Socialists have crossed swords over pot-smoking with their most likely coalition partner for the next five years, the Greens party. The discord surfaced this week when Housing Minister Cecile Duflot, head of the Greens party, said she backed the legalization of cannabis. Socialist Prime Minister Jean-Marc Ayrault, trying to put the matter to rest, said in a television interview that Hollande had opposed legalization of the soft drug during the presidential election campaign.
