King Charles is to call for unity and building bridges in what he describes as "these uncertain times" of international tension, in a message to mark Commonwealth Day next week. In the annual message to mark the day on Monday, the King will emphasise the value of nations coming together in a "spirit of support, and crucially, friendship".

King Charles hailed the work of the Commonwealth in bringing countries together as he and Britain's senior royals gathered at London's Westminster Abbey on Monday for the annual celebration of the international association he leads.

Britain's King Charles III made an appeal on Saturday for unity in "uncertain times", as the 76-year-old monarch emerges as a key figure in the UK's diplomatic drive over Ukraine.
