What has the Munich Security Conference achieved?

Western nations unite in support for Ukraine, as the US vice-president says Russia has carried out war crimes.

Also in the programme: a two-day African Union summit in the Ethiopian capital, Addis Ababa, begins today with food security at the top of the agenda; and we speak to David Gutenmacher, a New York-based photographer who finds old photographs and returns them to their owners.

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.
