The Queen has cancelled a trip to Northern Ireland on medical advice from doctors who have ordered her to "rest" ahead of COP26 later this month. 

According to Buckingham Palace, her Majesty "reluctantly accepted medical advice to rest for the next few days” and was in good spirits despite her disappointment at not being able to visit Northern Ireland. 

It comes as she is set to travel to Scotland later this month to attend COP26 - the biggest climate conference of the decade which will see heads of state from around the world descend on Glasgow. 

The 95-year-old monarch maintains a very busy schedule, having recently rejected the "Oldie of the Year" trophy on the belief "you are only as old as you feel". 

Here's what we know about the Northern Ireland cancellation and whether it will impact the Queen's trip to COP26...

Will the Queen still attend COP26?

Despite the cancellation of the Queen's Northern Ireland trip this week, she is still expected to attend COP26 later this month. 

Regarding the decision not to travel to Northern Ireland, a Buckingham Palace spokesman said: "The Queen has reluctantly accepted medical advice to rest for the next few days.

"Her Majesty is in good spirits and is disappointed that she will no longer be able to visit Northern Ireland, where she had been due to undertake a series of engagements today and tomorrow.

"The Queen sends her warmest good wishes to the people of Northern Ireland and looks forward to visiting in the future."

The Queen will stay at her residence at Holyrood Palace in Edinburgh throughout COP26, and is expected to be joined by her son and heir to the throne, Prince Charles. 

The conference follows a busy period for the long reigning monarch, who is due to celebrate her platinum jubilee next year. 

Last week, she was pictured using a walking stick for what is believed to be the first time at a major public event while attending a service marking the centenary of the Royal British Legion.
