Putin calls up reservists for war in Ukraine

In a televised address to the nation, he said this was a necessary step to ensure Russian territorial integrity. We hear reaction from Ukraine and Germany. Also on the programme: how the normally sedate world of top-level chess has been turned upside down this week by an extraordinary spat between the world champion Magnus Carlsen and a young US player, Hans Niemann.
