Joe Biden’s COP26 trip had already been somewhat marred by being flashed by a ‘large’ Scottish man and appearing to fall asleep during the speeches.
But the US president has now been hit with further embarrassing revelations concerning his brief visit to Glasgow.
Apparently the most powerful man in the world produced some of his own emissions at the summit, by farting audibly while chatting with the Duchess of Cornwall.
Camilla is said to have been so taken back by the incident that she won’t stop talking about it, The Mail on Sunday reported – citing an ‘informed source.’
Biden apparently proved his is truly Donald Trump’s successor while world leaders mingled in Glasgow.
He and Camilla were seen making small talk alongside foreign secretary Liz Truss during a reception on Monday at the city’s Kelvingrove Art Gallery.
The source said: ‘It was long and loud and impossible to ignore. Camilla hasn’t stopped talking about it.’
Biden, 78, this week marked a year since his victory in the presidential election but is facing a dwindling popularity rating.
He tried to use the COP summit to reassert his country’s willingness to take action on climate change after Trump withdrew from the Paris Agreement.
Driving on small Scottish roads on its way to the summit, Mr Biden’s massive motorcade came across a large, naked Scottish man who was stood in his front window taking a picture, according to the official White House pool report.
The journey in may have proven too much, as Biden was then seen appearing to briefly fall asleep during the opening speeches – in a much-shared clip.
During the long election campaign last year, questions were repeatedly asked about Biden’s ability to lead the country, given his age.
He was branded ‘sleepy Joe’ by his rival Donald Trump and his Republican rivals have made the most of every apparent lapse in concentration.
In his own address to world leaders, Biden promised that the US would lead in the fight against climate change by example instead of words.
‘None of us can escape the worst of what’s to come if we fail to cease this moment,’ Biden said.
‘We’re standing in an inflection point in world history.’
The White House refused to comment on the Mail on Sunday’s story.
