I'll copy below what I posted on a previous petition thread - my comments apply just the same to this thread
This petition is a bit of a dead duck. You need to lobby your MP's and get them on side, don't just email them make an appointment to see them at their local surgery and work on friends and colleagues to do likewise for you. Try to get in the local papers and radio.
12 years ago I was involved in a bit of a local campaign and must have met my MP (now Secretary of State) 5 or 6 times in as many months - They are there to represent you
I agree but I do feel that if people really want to get stuck in to the cause they need to front up to their MP - remember we pay their wages and expenses
