PMQs: Lucas calls for Grayling sacking over Southern strikes
Brighton MP Caroline Lucas calls for Chris Grayling to be sacked from his transport brief, and for the rail operator to lose the Southern Rail franchise.
The Green Party co-leader asked the prime minister: "Will she sack him, strip GTR of the franchise, and freeze fares for long-suffering passengers?"
Theresa May said the MP should be condemning the strike.
