US President Joe Biden appeared to doze off during the opening speeches of the Cop26 summit in Glasgow.
The 78-year-old, who was branded "Sleepy Joe" by rival Donald Trump on the campaign trail, seemed to nod off for more than 30 seconds before being interrupted by an aide who whispered something in his ear.
As Biden rested his eyes, the person speaking on stage said: "You have the chance to make decisions and reach an agreement which will affect the lives of generations to come. You are in positions of extraordinary power. You can change forever the trajectory that we are on."
At the end of the speech, Biden clapped along with the rest of the delegates.
