King Charles III to address nation as Britain starts national mourning

King Charles III, who automatically acceded to the British throne when Queen Elizabeth II died Thursday, will return to London from Balmoral Castle in Scotland to deliver an inaugural address on Friday. The televised speech is expected to stress the continuity of Britain's constitutional monarchy. Charles will also hold an audience with Prime Minister Liz Truss, who took office earlier this week. Parliament will gather to pay respects, with Truss leading tributes to the late queen in the House of Commons. It is all part of a meticulously planned transition, code-named Operation London Bridge, after the death of Britain's longest-serving monarch. The country is launching a national period of mourning with cannon salutes and bells tolling at Westminster Abbey,
