The Queen will not appoint the next prime minister in London, but will instead stay in Balmoral to do it, Buckingham Palace has said.
The new PM and Boris Johnson will go to Scotland, in a break from tradition for the event on 6 September.
During her 70-year-reign the Queen, 96, has had an audience with her new prime minister at Buckingham Palace.
It is understood that the decision was taken to provide certainty for the new prime minister’s diary.
The Queen has suffered from mobility issues and it is understood the change was made to prevent the need for any last-minute rearrangements.
Liz Truss or Rishi Sunak will be announced as leader of the Conservative Party on Monday, 5 September.
Boris Johnson is expected to announce his resignation to the Queen the following day, with his successor appointed by the monarch shortly after.
Buckingham Palace previously said the Queen would interrupt her stay at Balmoral to meet the new prime minister – the 15th of her 70-year reign.
