Defence Secretary Michael Fallon: Corbyn 'a risk to security'

Conservative Defence Secretary Michael Fallon has said the Labour party under Jeremy Corbyn presents a big "risk" to Britain's national and economic security.

Mr Corbyn won the leadership contest by an overwhelming majority, seeing off a challenge from frontbenchers Andy Burnham, Yvette Cooper and Liz Kendall.

Mr Fallon claimed all working people would be worse off under a Labour government.
