Johnson arrived back in Glasgow today, and he quickly got to business attending meetings for COP26’s Transport Day.
The Prime Minister travelled by train, after he was criticised last week for travelling to and from the conference via a private jet.
On arrival at Glasgow Central, he was escorted by police officers through the station.
Meanwhile, Congresswoman Alexandria Ocasio-Cortez posted on social media, expressing her desire to try Irn Bru.
Her wish was granted by First Minister Nicola Sturgeon who delivered a can of the fizzy drink to her at COP26.
On the eleventh day of the conference, Extinction Rebellion continued their action, by holding a candlelit vigil in George Square.
