You would see a major break in convention, with senior generals directly and publicly challenging Corbyn over vital, important policy decisions such as Trident, pulling out of Nato and any plans to emasculate and shrink the size of the armed forces.

The Army just would not stand for it. The general staff would not allow a prime minister to jeopardise the security of this country and I think people would use whatever means possible, fair or foul, to prevent that.
