With campaigns for both sides having started up, thought I'd open a thread for discussion of the UK's upcoming referendum to remain or leave the European Union.   In the words of The Buzzcocks Clash, should we stay or should we go?   Are you in a quandary to vote in favour of staying, even if that means siding with Tony Blair and David Cameron? Will Caroline Lucas' decision to vote for staying hurt any re-election chances she may have even if she is on the winning side? (See Labour in Scotland).   Would we be better off leaving? What happens if the constituent parts of the UK vote differently? What interventions can we expect from the international community?   So many questions distilled down to "Leave" or "Remain". Bound to be quite a few personalities involved and no doubt some social media abuse hurled about - like the Isle of Man flag, this thread has legs. Let's fire the starting pistol.
