The Tory minister defended Home Secretary Amber Rudd after she claimed a Labour government would lead to more terror attacks taking place in Britain.
Speaking on ITV’s Peston on Sunday, Sir Michael questioned Mr Corbyn’s voting record on anti-terror legislation during a grilling by host Robert Peston.
The presenter asked: “Amber Rudd has said that there would be more terror attacks if Jeremy Corbyn became Prime Minister, that’s disreputable alarmism, there’s no evidence for that whatsoever."
Sir Michael said: “Well, look at the man’s actions, not just his words.”
He was cut off by Mr Peston who asked: “More terror attacks?”

“And [who] has always questioned the nuclear deterrent and indeed our Nato deployments. We would certainly be less safe if Jeremy Corbyn was Prime Minister.”
The host then pressed the minister on whether the Tories’ “negative campaign” against Mr Corbyn would be to the party’s detriment.
But Sir Michael fired back and said: “We’re pointing out there is a very real risk of Jeremy Corbyn becoming Prime Minister of this country in less than two weeks time.
