French lawmakers will vote on Wednesday on no-confidence motions which are all but certain to oust the fragile coalition of Prime Minister Michel Barnier, deepening the political crisis in the euro zone's second-largest economy.

Michel Barnier's appointment comes after Macron and his Centrist Alliance faced a major loss in the legislative assembly elections.

Michel Barnier expressed hope for a 'reflex of responsibility' during a television interview when asked about his government's chances of surviving Wednesday's no-confidence vote in parliament.
