The Queen’s royal staff were reportedly called from across the UK to an emergency meeting at Buckingham Palace during the early morning.
The news, from "sources", sent the internet into meltdown as the monarch's aides and team members from as far as Balmoral in Scotland to her Sandringham Estate in Norfolk and Windsor Castle head to the city residence.
