PMQs: Cameron and Miliband on Pfizer AstraZeneca jobs

Labour leader Ed Miliband has called for the prime minister to give assurances on the future of AstraZeneca and possible job losses in Pfizer's bid for the UK firm.

David Cameron said the best thing thing to do was "get stuck in to seek the best possible guarantees" on British jobs, investment and science.

The pair clashed on job numbers and a possible break up of the firm, as they looked back to previous claims about the future of Cadbury and the Royal Mail.
