Daily SumUp

Canada's governing Liberal Party will announce on Sunday who will take over from Justin Trudeau as leader, after a crucial vote that will change the face of Canadian politics.

About 140,000 of the party's members have been voting for their preferred candidate, with results expected to be announced around 18:00 EDT (22:00 GMT).

The new leader will become the country's prime minister. But because the Liberals are a minority government, holding onto the top job will require winning a general election, which could be called in the coming weeks.

Whoever replaces Trudeau will have to grapple with US President Donald Trump's threats against Canada, which include an escalating trade war and repeated calls to make the country the US's "51st state".

The issue has dominated the campaigns of all four candidates vying for the top job. Here's what to know about them.
