King Charles III has voiced concern regarding a simmering separatist movement in western Canada during a meeting with Indigenous leaders, as one First Nation has sued Alberta arguing a potential referendum on separation violates indigenous rights.

First Nations chiefs across Alberta unanimously passed a vote of non-confidence in the Alberta government this week, citing concerns around the separatist movement and a failure to meet their treaty responsibilities.

One First Nation has sued the province of Alberta, arguing that allowing a possible referendum on separating from Canada is a violation of indigenous rights.

First Nations chiefs met at Buckingham Palace, making a case for Canada and reminding the public of the country's historical depth.
