News from Christopher Leslie, my MP, 3/4/12:
All sounds like good news, although at time of writing he has yet to sign the Early Day Motion that Andrew Griffiths has put forward. Have a look at it, and have a look if your MP has signed. If they haven't, drop them an email or a letter. In my experience MPs are usually happy to hear from constituents, and for the sake of a few minutes of your time, you can get them to make a difference. If you, or anyone else you know, needs more convincing, you should read Pete Brown's blog post on the subject. Signing the e-petition is a good thing, but I think letting your MP know about how you feel on this is a lot more powerful.
PS. I should probably have mentioned Find Your MP, in case you're not sure of who to write to.
