Mark Carney, a central banker turned politician, steps into his role at a crucial moment as President Trump sets his sights on Canada’s sovereignty and keeps threatening more tariffs.

King writes to new Canadian prime minister Mark Carney - Mr Carney paid tribute to Canada’s ‘proud British heritage’ in a speech after he was sworn in as the country’s new prime minister.

Sworn in at a ceremony in Ottawa on Friday, Mr Carney pledged his loyalty to Charles, who is also the King of Canada, and later lauded Canada's "proud British heritage" in his address.
