Diane Abbott: US cannot act as 'world police'

Labour MP Diane Abbott says the only legal way to bomb Syria would be with a UN resolution.

The shadow public health minister said diplomatic pressure on Syria's allies Russia and China should be stepped up.

Ms Abbott added there was a danger that Britain would be "sucked into a Syrian civil war".

She also alluded to the fact she may reassess her role if unsatisfied with a government motion on military action, saying "If the motion is a blank cheque for military action it would put some of us in a very difficult position."
