French president Emmanuel Macron has appointed defence minister Sebastien Lecornu as the country’s new prime minister, the fourth in approximately a year.

Mr Lecornu, 39, is the youngest defence minister in French history and architect of a major military build-up through to 2030, spurred on by Russia’s war in Ukraine.
