Boris Johnson failed to protect biodiversity hotspot, says UN expert

Ocean advocate highlights lack of action over South Georgia and the Sandwich Islands

Lewis Pugh, who in his role raises awareness about the state of the world's oceans, has worked with three of the rivals in the Tory leadership race - Michael Gove as environment secretary and both Jeremy Hunt and Boris Johnson as foreign secretaries - but highlighted Johnson's lack of action.
