Nearly 500 dignitaries from around the world are set to descend on London to pay their last respects to Queen Elizabeth II at a full state funeral at Westminster Abbey on Monday.
They will join members of the Royal family, UK prime ministers past and present, and key figures from public life in one of the largest diplomatic moments of the century.
“This is the biggest international event we have hosted in decades,” a Whitehall source said.
The source compared the logistical task to organising “hundreds of state visits” within a matter of days. Normally, there might only be two or three a year.
It presents a huge logistical, diplomatic and security challenge, with practice runs taking place in the dead of night.
So, who can we expect to see attend Her Majesty’s funeral?
The Royal family
The late Queen’s four children – King Charles III, Princess Anne, Prince Andrew and Prince Edward – will be present at the funeral, as well as their respective spouses: Camilla, the Queen Consort; Sophie, Countess of Wessex and Sir Tim Laurence. The Duke of York’s ex-wife, Sarah Ferguson, is also expected to attend.
The late Queen’s grandchildren will also be in attendance at the service - Prince William, Price Harry, Peter Phillips, Zara Tindall, Princess Beatrice, Princess Eugenie, Lady Louise Windsor and James, Viscount Severn.
Spouses of close family, including Catherine, the Princess of Wales and Meghan, the Duchess of Sussex will pay their respects too.
