David Cameron says he is prepared to work with Vladimir Putin to defeat Islamic State, but also warns that President Bashar al Assad "cannot stay as leader" in Syria.
The Prime Minister and the Russian President are among the leaders attending the United Nations General Assembly in New York.
Mr Cameron hopes to use the opportunity to "inject momentum" into finding a political solution to the Syrian conflict which has claimed 200,000 lives and displaced 11 million people.
