People in London waited in kilometres-long lines for the chance to pay their respects to Queen Elizabeth II, Britain's longest reigning monarch who died on Sept. 8, during her lying-in-state. Hundreds of leaders, dignitaries and royals travelled from around the world to attend her funeral. Queen Elizabeth II was just 25 when she took the throne in 1952. At 73, King Charles III — the Queen's son and longtime heir — is the oldest monarch to assume the British throne. Today on Front Burner, Stephen Bates, author and former religious affairs and royal correspondent for The Guardian, takes us through what's shaped King Charles's character and what his reign could mean for the future of the British monarchy.
