HM Queen Elizabeth II's funeral will be held on Monday 19th September 2022.
The late monarch's funeral will take place at Westminster Abbey in London, Buckingham Palace has confirmed.
It has also been confirmed that the day of the funeral will be a Bank Holiday.
The Queen will lay in state for four days before her funeral on 19 September.
She will be taken from Buckingham Palace to Westminster Hall on Wednesday, where the coffin will be rested on a raised platform, known as a catafalque.
Her coffin will be draped in the Royal Standard flag and once in Westminster Hall it will be topped with the Imperial State Crown, orb and sceptre.
Members of the public will then be able to file past and pay their respects.
The grand hall is the oldest part of the Palace of Westminster, at the heart of the British government.
The last member of the Royal Family to lie in state in the hall was the Queen Mother in 2002, when more than 200,000 people queued to view her coffin.
Princess Anne will accompany Queen Elizabeth II's body to London ahead of the funeral, Buckingham Palace says.
The coffin will depart for Edinburgh airport on Tuesday and then be flown to London by RAF Northolt, with the Queen's only daughter on board.
The coffin is expected to arrive at Buckingham Palace at 20:00 GMT on Tuesday, where King Charles III and Queen Camilla will witness its arrival.
Westminster Abbey is where Britain's kings and queens are crowned, and where Queen Elizabeth II married Prince Philip in 1947.
Heads of state from across the world will be invited to join members of the Royal Family to remember the life and service of the Queen.
Senior UK politicians and former prime ministers are also expected to attend the service, which will be televised.
The service will likely be conducted by the Dean of Westminster David Hoyle, with the Archbishop of Canterbury Justin Welby giving the sermon. Prime Minister Liz Truss may be called on to read a lesson.
The Queen's funeral will be the first state funeral since Sir Winston Churchill in 1965.
