A member of French energy giant EDF's management board resigned Thursday just before a key meeting on the future of a British nuclear project, saying he disagreed with the plan.

In a letter seen by AFP, Gerard Magnin, who was invited by the government to join the board in 2014, said he could no longer support France's strategy to push nuclear energy at the expense of other options.

A deeply divided EDF board is to vote later Thursday on a controversial project to build a nuclear power station at Hinkley Point in Britain which critics say could bankrupt the French utility.
