My new MP has written me a letter, which I'll check in detail when I'm back in the UK next month - inshallah. He says he doesn't sign EDMs (although I see his name against 4 others on that very useful website) but goes on to detail the steps he intends taking in support of the campaign.
So a conditional 'hurrah' then - much better than the previous incumbent (revealed to have been the SW's most expensive-to-run MP) who never bothered to reply and didn't even have an email address.
