My MP Libdem, signed the recent MEAssociation petition, has talked to me at length by phone, is sympathetic, and we are meeting after the summer to discuss further.
@AndyPR - we had a Conservative MP until the recent election. We did involve him and he wrote letters. Achieved by my husband writing very carefully worded letters and being very persistent. It took hours and hours. I honestly wouldn't have had the energy myself. They were letters not tweets. I do feel that modern modes of communication like email and tweet may not be as successful until a relationship has been made.
I do agree with those who believe we have to get MPs working for us but it is hard work.
