Other senior ministers as well as COP26 president Alok Sharma will still represent the UK at the climate summit in Sharm El Sheikh, the statement said.
“The Government is fully committed to supporting COP27 and leading international action to tackle climate change and protect nature,” a Downing Street spokesman said.
“The Prime Minister is not expected to attend the summit in Egypt due to other pressing domestic commitments, including preparations for the Autumn Statement.”
Sharma and the senior ministers present will continue to strive to ensure that countries continue to make progress on the commitments made at COP26 in Glasgow, the statement added.
The news comes after British media reported in early October that King Charles III, the famous environmentalist, would miss COP27 after then-Prime Minister Liz Truss advised him to abandon plans to attend.
CNN understands the monarch’s attendance at COP27 has not been confirmed and, after consultation with the government, a joint agreement was reached that it would not be an appropriate occasion for Charles’ first overseas visit as sovereign.
King Charles will attend the Climate Change Conference in 2021 as the Prince of Wales.
