Justin Trudeau has announced he will step down after nine years as Canadian prime minister in the face of a mounting set of crises, but stay in office until a replacement party leader is chosen.

Trudeau announced his resignation after facing an increasing loss of support from both within his party and in the country.

Announcing his resignation on Monday, Trudeau said he planned to stay on as prime minister until a new party leader is selected. Who will succeed him — and can they survive a looming no-confidence vote?
