The French presidency has traditionally had a mythical quality. As father – or in theory, at least – mother of the nation, the person who incarnates the French republic is supposed to be above party politics and – rather more controversially – above the law. But as voters prepare to choose their president for the next five years, the institution is in danger of slipping into irrelevance. Much depends on the result of presidential voting this month and next and, more importantly perhaps, of the June legislative elections.
