This seems to have been a bit like the "Hokey Cokey -In, Out, shake it all about" for much of the time. Our group started with Leave.EU, some of us joined Vote Leave when it started and then later there was Grassroots Out when they came along and swept up Leave.EU under their banner and UKIP for a while. We joined them too and while they slugged it out to win the "offcial" designation contest, won eventually by Vote Leaveto no great surprise (the Establishment strikes again!) we decided to create our own distinctive Milton Keynes brand of "all of the above, and none of them", as represented by the "Stickman".
In the end Leave.EU are still going on and I have some doubts about Vote Leave, so its just as well really that I never got round to changing all the logos on the pages!
