Good Morning Britain's Susanna Reid was caught in a fiery clash with a Tory MP live on the ITV show today.
Conservative MP Grant Shapps - the Transport Secretary - appeared on the programme to discuss the new photo, which saw Mr Johnson raising a glass with a number of people. Bottles of alcohol were also seen on a table nearby.
In the chat, Mr Shapps claimed that a small detail in the background of a new photo of Boris Johnson drinking with colleagues proves he was working and not partying at the time. He had said that the ministerial boxes could be seen in the back of the photo and that there was no way Mr Johnson would bring them to a party, and thus it was a work event.
