Against the backdrop of artillery salutes at one-minute intervals, the solemn procession paid tribute to the late Queen, who was Britain's head of state for 70 years.

King Charles III and Elizabeth II's other children - Princess Anne, Prince Andrew and Prince Edward - walk in the front row behind the gun carriage carrying the Queen's oak coffin.

The second row is made up of the two sons of King Charles III, Prince William, Prince of Wales, and Prince Harry, Duke of Sussex.

To Harry's left is Anne's son, Peter Phillips.

Behind them are the Earl of Snowden, the Duke of Gloucester and Vice Admiral Sir Tim Lawrence, who is Princess Anne's husband.

Behind the royals are four key members of King Charles III's staff: the host, the principal private secretary, the aide-de-camp and the treasurer.

Prince William's aide-de-camp walks behind them.

The Royal Horse Artillery marks the final departure of Queen Elizabeth II from Buckingham Palace.

Cannons echo at one-minute intervals as her coffin travels to Westminster Hall, where it will lie in state.

Big Ben - the great legendary bell that sits in the Elizabeth Tower - also chimes at one-minute intervals during the procession.

The bell and its tower are undergoing restoration, and the ringing is the longest since these activities began.

Britain is in mourning for Queen Elizabeth II, who died last week at her summer residence in Scotland at the age of 96 after 70 years on the throne.

She was succeeded on the throne by her eldest son, King Charles III.
