I'm a labour member, I have been since 2012 but I've considered leaving. Meanwhile I'm a member of the Conservative party, I'm not sure if that's allowed but it worked. I was a member of the liberal dems tills 2015 when their election defeat made them more or less useless although they do have the best conference week by miles. I'm quite active amongst my local Conservative party, we have dinner and lunch a lot (3-6 times a month) and discusss great things with great opportunities to get involved, with labour I've found they just spam you, beg you to campaign and donate money but do nothing to bring the community closer or interesting.
