Leaders from across the world have gathered in Egypt for the Cop27 conference.
The conference made headlines last month when PM Rishi Sunak announced that he would not attend, and would stay in the UK to focus on national issues. The decision was heavily criticised by environmental groups and members of his own party, eventually causing Mr Sunak to u-turn on his announcement, and he has joined other world leaders in Egypt.
His attendance at the gathering in the Red Sea resort of Sharm El-Sheikh alongside leaders such as US President Joe Biden and French President Emmanuel Macron marks his first outing on the international stage since becoming Prime Minister last month. This will also be the first time the UK will negotiate at climate talks on its own, rather than as part of the EU.
