In a speech after winning the Liberal leadership contest, Mark Carney called the U.S. a 'country we can no longer trust' as he outlined his plans for tackling U.S. tariffs.

Carney will become Canada's prime minister after the governing Liberal Party elected him its leader in a landslide vote.

Carney, 59, will be taking on the reins of his country at a time when it is locked in a trade war with the U.S., its largest trade partner.
