Queen Elizabeth the Second's coffin will be delivered to London on Tuesday after a 24-hour stay at Edinburgh's historic cathedral, where her son King Charles the Third and his three siblings held a silent vigil, Reuters reported.

Charles was joined by his sister Anne and brothers Andrew and Edward for a 10-minute vigil Monday at St. Giles Cathedral, where they stood, heads bowed, on four sides of the casket as members of the public passed by to pay their respects.

Queen Elizabeth the Second died Sept. 8 in Balmoral at age 96 after a 70-year reign, plunging the nation into mourning.

Charles, 73, who automatically became king of the United Kingdom and 14 other kingdoms, including Australia, Canada, Jamaica and New Zealand, is traveling to four parts of the United Kingdom before the funeral and will visit Northern Ireland on Tuesday.

In Belfast he will meet with senior politicians and religious leaders and attend a service at the city's St. Anne's Cathedral before returning to London.

The Queen's coffin will leave Scotland for the first time since her death: it will be flown to London in the evening and then transported to Buckingham Palace.

On Wednesday it will be taken on a carriage as part of a grand military procession to Westminster Hall, where it will remain until September 19, the day of the funeral.
