In the past on when your Smiling Tony was in power the UK pushed for a lot of restrictive weapon laws at  EU level. Not much ever came of that  because it was either to retarded or it didnt solve any problems.

In recent times the UK did not bother as much but it seems to be on the agenda again to try and export your retarded gun laws. As far as I know Cameron is the first national leader to support this, the EU ban had some support from freedom hating parties  like the French Green Party

Please contact you MP's and MEP's  and help not make like miserable for the rest of Europe

Oh BTW the EU ban would also ban the UK semi auto .22LR's (still UK legal I think)
