Mp Diane Abbott asked on the 27th of November at PMQs:
The Prime Minister will be aware that the Mayor of London, Boris Johnson, proposes to close nearly every single ticket office on the London Underground network, with more than 700 jobs being lost. Does the Prime Minister believe that that is the way to raise living standards for ordinary Londoners?
Prime Minister David Cameron responded:
The best way to help Londoners is to ensure that we have a safe and affordable tube, and that we use modern technology to deliver that. The conversation that the hon. Lady needs to have is with the trade union that has done so much damage to our underground. We ought to have no-strike deals on the underground and permanent systems that provide a good service.
