George Galloway shared his thoughts on Boris Johnson to a caller on his show.
The Foreign Secretary ascended to his position in the wake of the EU referendum result to leave the European Union.
He has subsequently been dragged into the Brexit debate, with many suggestion he wilfully spread misinformation in the run-up to the Brexit vote.
Galloway certainly had some harsh words for the former Mayor of London, saying: "Johnson has some charisma but has many negatives.
"He has many skeletons in his cupboard, not all of which have tumbled out."
