Thousands of members of the armed forces from the UK and abroad are preparing to take part in the state funeral of Queen Elizabeth II - one of the grandest ceremonial events in living memory.

A procession involving the military, the Royal Family and those who have dedicated their lives to service of the Queen, will give the late monarch a final farewell full of pomp and pageantry ahead of her burial in Windsor.

Here's everything you need to know about the main funeral cortege.

Thousands of members of the military from the UK and the Commonwealth will be marching through London and Windsor. They'll be taking part in the processions, lining the route, providing guards of honour or undertaking other ceremonial duties.

The Queen, who was head of the armed forces and served as their commander-in-chief, had a close personal relationship with the military and they will accompany her coffin in three processions on its journey through London to Windsor Castle - its final resting place.

The first, and shortest, will take her coffin to Westminster Abbey for the funeral service, the second will transport her from the Abbey to Wellington Arch ready for her road journey to Windsor. Once in Windsor, her coffin will join a third procession to St George's Chapel in the castle's grounds.

But the main focus will be the second, the journey through central London after her funeral, when the cortege, led by the Royal Canadian Mounted Police, will be made up of seven groups, each with its own band. Members of the armed services from the UK and the Commonwealth, the police and the NHS will also be involved. It is expected to leave the Abbey just after midday and last about 45 minutes.

The Queen's coffin, topped with the Royal Standard and Imperial State Crown, will be at the centre of the procession carried on the State Gun Carriage of the Royal Navy. The carriage was last seen in 1979 for the funeral of Prince Philip's uncle, Lord Mountbatten, and was used for the Queen's father, George VI, in 1952.

She will be accompanied by the bearer party of the Grenadier Guards, the King's Body Guards of the Honourable Corps of Gentlemen at Arms, the Yeomen of the Guard and the Royal Company of Archers.

Senior members of the Royal Family, including the new King and his sons Prince William and Prince Harry, will follow behind.

They will be joined by members of the Royal Household.

Camilla, the Queen Consort, the Princess of Wales, the Countess of Wessex and the Duchess of Sussex will join the procession in cars.

Once the procession reaches Wellington Arch at Hyde Park Corner, at about 13:00 BST, the coffin will be transferred to the new State Hearse for its final journey to Windsor Castle.

Just after 15:00 BST, the hearse is expected to arrive for a walking procession up Windsor Castle's Long Walk. The three-mile (5km) avenue will be lined with members of the armed forces.

The King and senior members of the Royal Family are expected to join the cortege in the Quadrangle in Windsor Castle a little later ready for the committal service and later burial at St George's Chapel.
