Today has been an extraordinary test of endurance for Britain’s 73 year-old incoming king, who addressed Parliament in London for the first time, before heading to Scotland to commence his jam-packed tour of all four nations that make up the UK.

This morning, Charles III was greeted by a sombre sea of black – comprised of 900 MPs and peers – at Westminster Hall, the oldest existing part of the Palace of Westminster, where the Queen’s coffin will soon lie in state for public viewing.

Speaking to both Houses of Parliament, he vowed to follow his late mother’s “selfless duty” before praising Parliament as the “living and breathing instrument of our democracy”.
