The King will not be attending COP27 in Egypt next month, according to reports.
His Majesty, a keen climate activist, had been planning to deliver a speech to world leaders at the event in Sharm el-Sheikh, the Times reported, but had been warned by Prime Minister Liz Truss to “stay away”.
Meanwhile Sky News reports that the decision for the monarch not to attend was made “in consultation” with Ms Truss.
A Number 10 source told Sky News: “The idea the PM gives orders to the King is ridiculous.”
King Charles III had intended to attend COP27 in person, but planned to consult Ms Truss about this following the official mourning period after his mother’s death.
A close source said at the time: “The King and the Prince of Wales care deeply about our planet. That won’t change now he is King. But the King, as head of state, will seek clarification about his possible attendance from the Prime Minister before taking a decision over COP27.”
King Charles has attended the UN climate conference for years as Prince of Wales and delivered one of the keynote speeches at the opening ceremony for COP2 in Glasgow last year.
Speaking at the opening of COP26, Charles called on world leaders to adopt a “warlike footing” to deal with the threat of climate change. He also delivered the opening speech at COP21 in Paris in 2015.
The late Queen also gave a speech at the event via video link.
His slimmed-down coronation could take place in May or June next year at Westminster Abbey. It has been suggested it might fall on the same date as his mother’s ceremony, which was on June 2, 1953.
The new King and Prime Minister met at Buckingham Palace shortly after the Queen passed away.
