After taking questions from journalists about the outcome of the talks, Boris Johnson also took some flack online for suggesting the COP26 summit took place in Edinburgh rather than Glasgow.
The Prime Minister was facing questions from journalists over the outcome of the climate conference, but appeared to forget the talks which he was officially ‘hosting,' were in Scotland's second city and not the capital.
Johnson was appearing alongside COP26 president Alok Sharma at a special press conference on Sunday when asked a question about UN secretary general António Guterres and his reaction to the outcome.
“I don’t think António would want people to think that we’ve cracked it here at COP in Edinburgh, of course not," he said.
The gaffe has since been relentlessly mocked on social media, with users pointing out the similarities with CNN anchor Wolf Blitzer - who tweeted about heading up the broadcaster’s coverage of the event in front of Edinburgh Castle.
One person tweeted: "All the world leaders and delegates saying how impressed they were with Glasgow, both in its holding of Cop26 and the city itself. Our own Prime Minister, Boris Johnson doesn't even know it was in Glasgow. It's depressing, it really is."
Another wrote: "No wonder Boris Johnson didn't come to the end discussions of COP26. He thought it was in Edinburgh!!"
At the conference world leaders eventually agreed on a deal that explicitly details a move away from coal power on Saturday evening, however the pact has come in for criticism for falling short of an accord that would limit temperature rises to below 1.5C after a late rewording.
At the same press conference where he made the geographical gaffe, Mr Johnson said the summit “sounded the death knell for coal power,” but acknowledged his delight at progress made was “tinged with disappointment”.
