Unspun World: Is it time to return looted art?

What should we done with stolen treasures? The BBC's culture editor, Katie Razzall, confronts colonialism's legacy with world affairs editor John Simpson. John also finds out if victory is finally in sight for the Ukrainians. Security correspondent Frank Gardner thinks it might be if they can push past the Russians' strong defences - but not all Ukrainians are up for fighting. Eastern Europe correspondent Nick Thorpe has been on the trail of those who risk life and limb to escape the front line. Plus, who might fill the vacuum left by first French and now UN troops leaving Mali - Wagner or jihadis? Beverly Ochieng from BBC Monitoring reveals a precarious state of affairs.
