UN Secretary General Antonio Guterres delivered an unexpected moment of levity at the COP27 climate conference on Wednesday, reading the beginning of the wrong speech before realising, chuckling and starting again with a different opening line.

Speaking in the main plenary hall of the Sharm el-Sheikh conference on Wednesday, Guterres was due to give the opening address at a session with former U.S. Vice President Al Gore on tracking carbon emissions.

Guterres explained that he was due to speak to a group of young people after his address, and had begun reading the speech aimed at them instead.

“There was a small confusion, I apologize.
