On thing that wasn't mentioned during the whole campaign from any of the parties was the military (apart from Trident). But who was is the country turned to recently when the national terror threat was elevated, or when G4S cocked up at the Olympics in 2012? Remember the fuel strikes back in 2000 when military personnel were used to escort fuel trucks from the refinery, or the Fire Service strikes in 2002?
If Corbyn gets his way, the military is going to get decimated, and you certainly aren't going to get the police force to be able to undertake the same roles, however much of the money saved on the military is thrown at them.
