PARIS - President Emmanuel Macron will convene a meeting of France's mainstream political parties on Friday ahead of a self-imposed deadline to name a new prime minister, as the country's central bank chief warned the political crisis was curbing growth.

Macron is searching for his sixth prime minister in under two years and will need to find a personality whose appeal spans the centre-right to centre-left in order to steer a budget through a fragmented and fractured parliament.
