Queen’s coffin arrives in Edinburgh, Scotland

King Charles III arrived at Buckingham Palace on Sunday afternoon, after major cities across the UK held public proclamations announcing his accession to the British throne.

Royal fans waved Union Jack flags to greet the King, who returned to the famous London residence at around 1:00 p.m. local time (8:00 a.m. ET).

He is expected to hold audiences at Buckingham Palace with religious and Commonwealth leaders, according to a palace statement.

The King is due to receive the secretary-general of the Commonwealth and the Dean of Windsor, Buckingham Palace said. He will also attend a reception with realm high commissioners.

Earlier today, public proclamations to King Charles III took place in the cities of Edinburgh, in Scotland, Belfast, in Northern Ireland and Cardiff, in Wales.

The public proclamations are traditional ceremonies announcing the accession of the new monarch.

Charles was formally confirmed as the new King of the United Kingdom during a ceremony at St. James’s Palace on Saturday.
