Ukrainian refugees still arriving in Poland

As the first anniversary of the start of the war approaches, many Ukrainians continue to leave the country. The BBC's Sarah Rainsford has been to meet some of them in Poland, and others who have been there since the conflict began. Also in the programme: at the Munich Security Conference Western nations unite in their support for Ukraine, as the US vice-president says Russia has carried out war crimes; and adverts for natural gas are all over social media, but how clean is it as an energy source?

Joining Paul Henley to discuss these and other stories are Julia Buxton, a professor of criminology specialising in international drug policy at the University of Manchester, and Christopher de Bellaigue, a British journalist, author and historian.
