Syrian dictator told a delegation of MPs that Russian president Vladimir Putin will not let him "lose", a senior Tory said
David Davis MP, who was part of the delegation, described the brutal leader as "polite and courteous" but added that he "sidestepped the barrel bomb issue."
"He said Putin said 'we will not let you lose', which for me was the most important phrase of the entire visit because that actually defines what the outcomes are going to be," Davis told to the BBC's Show.
"If the Russians will not let them lose, then there are two possible outcomes, the jihadist victory, which would be a disaster in my view by the way, the jihadist victory is not on the cards. Either a negotiated outcome or a Syrian victory is on the cards."
Last month, Russia made the surprising announcement that it would pull its troops out of Syria.
Protests against the Assad regime flared up during the Arab Spring and escalated into a full-blown civil war that has left hundreds of thousands of Syrians dead.
Assad has previously denied using chemical weapons and barrel bombs on civilian neighbourhoods during the conflict.
