Of course we would! Granted we're a well populated island but we're an island atleast, I think we'd stand a better chance than Americans :P
Of course! Every country, society, place has survivalist nut jobs don't they?! hahaha
Well, the few Brits I've met have been badasses, so I guess they have a chance - though they'll probably have to take a few hints from their little brothers across the pond, 'cause, well, we're just really good at killing prettymuch everyone and everything, so yeah.
Also, if at all possible, please take back Chef Ramsey - we can't handle him screaming at us anymore.
The British will survive. Not all of them but those who use their heads and their assets. Humans all over the world will survive. Urban areas will be the danger zones. There is always disease and sickness where large amounts of people gather. Most government assets will go to urban areas too. That is why government assets will be wasted n the dead. People will bring their sick and infected to the government centers. Riots will breack out and after a short time chaos will rule in the urban areas. Groups of live humans will become as dangerous as the zeds.
Although the countryside will have less dangers there will be dangers all the same. when the cities are no longer a viable source for survival then the masses, human raiders and zeds will turn to the countryside. Nowhere will be safe, only safer.
