A member of Liz Truss's cabinet said that King Charles should attend the climate change conference.
The prime minister was accused of ordering the King not to attend.
The King won't be attending the summit in Egypt.
The King championed the environment for a long time, and other countries wanted him to attend.
The former business secretary said that he would like to see His Majesty attend and that he was receiving a message from countries around the world.
He is the head of state in the United Kingdom but he is also the head of state in a number of other countries that are on the front line of climate change.
Buckingham Palace said the decision for King Charles not to attendCOP 27 had been made "with mutual friendship and respect" after he asked the prime minister's advice.
The monarch had been a huge global champion of the environment and tackling climate change long before it was a mainstream issue, Mr. Sharma said, but he couldn't comment on the contents of the conversations between the king and prime minister.
During the opening ceremony of last year's summit, the King made a speech about the importance of climate change.
The UK may not have a head of government or a head of state in attendance at the upcoming COP 27.
The prime minister has made it clear that the government will reach a net zero emissions target by the year 2050.
