"The party of Margaret Thatcher is long gone."
The party of MT banned semi-automatic rifles (except for 22 rimfire) after the Hungerford shootings of 1987.
The party of John Major (her Conservative successor) banned most handguns (including mine) ten years ago after the Dunblaine school shootings. I can't seem to be able to post links but you can find out about most of this on wikipedia (UK gun politics).
You haven't got a friend in the world over there. Good luck and best wishes to you. It would make me insane if I had to live there. The natural beauty must be what compels you to stay.
