Her Majesty Queen Elizabeth II – a day-by-day guide of what is happening this week

King Charles III was formally proclaimed King at a ceremony on Saturday steeped in ancient history, following the death of his mother, Queen Elizabeth II.

He automatically became King on her death on Thursday, but the Accession Council, attended by Privy Councillors, confirmed his role on Saturday morning.

A period of royal mourning will be observed from now until the end of the day of Queen’s funeral, which will be held on Monday, September 19, at Westminster Abbey.

The day of the funeral has also been declared a Bank Holiday by King Charles III.

What has happened so far this week:

Monday, September 12:

• Lords and Commons gathered for Motion of Condolence

• King and Queen Consort travelled to Edinburgh
• Procession from the Palace of Holyroodhouse to Saint Giles Cathedral.
• Crown of Scotland placed on Queen's coffin

Tuesday, September 13:

• King flew to Belfast
• 6pm: Queen’s coffin flown from Edinburgh Airport to RAF Northolt

What will happen for the rest of the period of national mourning:

Wednesday, September 14:

• Queen lying in state begins in Westminster Hall for four days. It will end at 6.30am on the morning of the Queen's funeral – Monday, September 19.
• Hundreds of thousands of people are expected to file past the coffin on its catafalque and pay their respects, just as they did for the Queen Mother’s lying in state in 2002.

Thursday, September 15:

• Lying in state continues and a rehearsal is likely to take place for the state funeral procession.

Friday, September 16 – Sunday, September 18:

• Lying in state continues, ending at 6.30am Monday morning. Heads of state begin to arrive for the funeral.

Monday, September 19:

The Queen’s state funeral will take place at Westminster Abbey in central London at 11am.

The original plans are for the Queen’s coffin to process on a gun carriage to the Abbey, pulled by naval ratings – sailors – using ropes rather than horses.

Senior members of the family are expected to poignantly follow behind – just like they did for the funeral of Diana, Princess of Wales, and for Prince Philip, the Duke of Edinburgh.

The military will line the streets and also join the procession.

Heads of state, prime ministers and presidents, European royals and key figures from public life will be invited to gather in the Abbey, which can hold a congregation of 2,000.

The service will be televised, and a national two minutes’ silence is expected to be held.

The same day as the funeral, the Queen’s coffin will be taken to St George’s Chapel at Windsor Castle for a televised committal service.

Later in the evening, there will be a private interment service with senior members of the royal family.

The Queen’s final resting place will be the King George VI memorial chapel, an annex to the main chapel – where her mother and father were buried, alongside the ashes of her sister, Princess Margaret.
