On the fifth day following the death of Queen Elizabeth II her body will return to London and the King will travel to Northern Ireland.
Intricate plans were drawn, codenamed Operation London Bridge, for when Queen Elizabeth died, which sees a number of events happen during a period of mourning. On D-Day +4, which is one day behind schedule due to the time The Queen's death was announced in Balmoral, a number of events are expected to take place across the United Kingdom.
Yesterday saw King Charles III make his first address as monarch to MPs and peers in Parliament. Later, he led a procession along Edinburgh's Royal Mile to St Giles' Cathedral, where the Queen's coffin is lying in state. Last night King Charles - alongside Princess Anne and Princes Andrew and Edward - held a moving vigil, standing watch over their mother's coffin.
