Future king Charles heads to Canada on queen's behalf

Memorials have sprung up in Canada after the discovery of the unmarked graves of Indigenous children over the last year

Prince Charles heads to Canada this week to represent head of state Queen Elizabeth II, with more attention than ever on his future role due to his mother's age and failing health.

His visit to Canada comes as part of a series by senior royals to some of the 14 Commonwealth countries outside the UK where the queen is also head of state.
