‘The most beautiful place on the planet’

It came after the Queen broke with convention earlier this summer when inspecting a guard of honour to officially mark taking up residence at her Scottish home.

Traditionally she inspects the guard of honour at the gates of Balmoral but this year she held the event privately within the estate’s grounds for her “comfort”, sources said.

Princess Eugenie, the Queen’s granddaughter, once described Balmoral as the most beautiful place on the planet.

“Walks, picnics, dogs – a lot of dogs, there’s always dogs – and people coming in and out all the time,” she said.

“It’s a lovely base for Granny and Grandpa, for us to come and see them up there; where you just have room to breathe and run.”

Queen said never to be happier than when staying at Balmoral

Balmoral has long been one of the Queen’s favourite places and she is said to never be happier than when staying there.

She travels to the estate in Aberdeenshire each summer, with members of her family invited to spend time with her while she is there.

Balmoral Castle was handed down to her through generations of royals after being bought for Queen Victoria by Prince Albert in 1852.

The Queen’s traditional annual stay at the main property – after a break at Craigowan Lodge on the estate in July – usually stretches through August and September and into October.

This year she travelled to Balmoral on July 21 and remained at the estate to appoint a new prime minister there for the first time in her reign on Tuesday.

The 96-year-old monarch, who has faced ongoing mobility issues, traditionally holds audiences with outgoing and incoming premiers at Buckingham Palace but this year stayed in Scotland.

Outgoing prime minister Boris Johnson and his successor Liz Truss made the 1,000-mile round trip to Aberdeenshire for the key audiences this week.

Queen recently spent more than three months resting on doctors’ orders

In recognition of her increasing frailty, Buckingham Palace has indicated that the public can no longer assume they will see her at public engagements, with her attendance only confirmed on the day in question.

She recently spent more than three months resting on doctors’ orders.

In October, a trip to Northern Ireland was cancelled and she spent a night in hospital for what a spokesman described at the time as “preliminary investigations.”

The Queen also pulled out of attending the Cop26 climate change summit, the Festival of Remembrance and then the Remembrance Sunday Cenotaph service due to a sprained back, and missed the Church of England’s General Synod. Last month, she missed the traditional Maundy Thursday and Easter Mattins church services at St George’s Chapel, Windsor.
