Prime Minister Liz Truss has reportedly blocked King Charles from making an appearance at the upcoming COP27 climate talks.
The annual gathering of nations to discuss the global environment is due to take place in Sharm El Sheikh, Egypt in November.
During his time as the Prince of Wales, Charles often spoke about the issue of climate change and his desire for creating a sustainable world.
In September 2021, he wrote exclusively for the Daily Mirror on his personal lifelong quest to help future generations and said: “I have spent some forty years of my life trying to indicate what needs to be done to ensure we do not bequeath a destroyed world to our children and grandchildren.”
He went on to warn that the world was "on the brink".
It was thought the King would be delivering a speech at this year's conference but the prime minister is believed to have rejected the idea - Ms Truss herself is unlikely to attend.
A senior royal insider told The Times : "It is no mystery that the King was invited to go there. He had to think very carefully about what steps to take for his first overseas tour, and he is not going to be attending Cop."
It is said the choice to stop the King attending the meeting was due to Government advice, although Charles will find other means to support the event.
The COP events are also know as the United Nations Climate Change Conference this year runs between November 6 and 18.
At last year's COP26 in Glasgow the then-Prince of Wales gave a speech before urging world leaders to unite together and tackle climate change.
But since the death of Queen Elizabeth II in September, the monarch has intimated that his role would change and some saw this as him potentially turning more apolitical.
The Queen also gave a speech at COP26, which The Times source described as "entirely non-political" and called it an "error of judgment" by the Government not to allow the King to attend.
