As the trade war between the once best friends continues, ex-Bank of England boss Mark Carney will be Canada's next PM in a widely expected victory.

Carney, 59, a political novice, will take over at a tumultuous time in Canada, which is in the midst of a trade war with the United States.

Mark Carney was elected as Justin Trudeau's successor after Liberal Party members voted in a nominating contest. Trudeau resigned in January, months after facing a stiff internal revolt with demands for him to step down.
