Prime Minister Boris Johnson has said he fears Vladimir Putin may deploy chemical weapons in Ukraine as that would be "straight out of Russia's playbook".

Speaking on Sky News' Beth Rigby Interviews... the Prime Minister said the only way the war in Ukraine can end is if the Russian President realises he has made a "catastrophic mistake".

Beth Rigby is also joined by Marina Litvinenko, the widow of former Russian agent Alexander Litvinenko who was poisoned in London, and Labour MP and mother of the House, Harriet Harman.
