The Queen plans to interrupt her Scottish holiday to travel to England and invite her 15th Prime Minister to form a government, The Mail on Sunday understands.
Boris Johnson has announced he will step down on September 6, when he will formally tender his resignation to the Queen.
The Monarch will then ‘invite’ the winning Tory candidate to become Prime Minister and announce their name.
The Queen, pictured on a visit to Edinburgh in June, is understood to be returning early from her annual Balmoral holiday to England in order to see in the new Prime Minister
They are expected to meet the Queen to officially accept the invitation.
The Queen does not usually return from her Balmoral break until early October but is believed to have told aides she will make an exception this year and travel to London.
A source said: ‘Her Majesty does not expect the new Prime Minister to travel to Scotland, so the plan is that the Queen will travel down to see them.’
The appointment of Prime Minister is one of the few personal prerogatives of the Queen and, sources say, a duty she intends to fulfil in person.
Buckingham Palace is seen as the official venue to host the appointments but, given the refurbishment works there, it may change to Windsor Castle.
The Queen’s visit to welcome the new Prime Minister is expected to be brief and she will return to Balmoral to continue her holiday.

Other aspects of her annual break have been scaled back this year, for example the cancellation of a public appearance and inspection of the guard before she takes residence in Balmoral.
