Exactly so. It's made perfectly clear onsite that only UK residents should sign, and that verifiable addresses MUST be given. Signatures from non-residents, or with incomplete addresses, will be providing a possible excuse for the petition to be ignored; as would signatures from Mickey Mouse, which I expect would also be "accepted" by the form.

Sorry and all, and the kind thought is appreciated, but for those who do not live in the UK, a short email to Kim Howells (address above) pointing out the potential damage to the tourist trade would probably be most effective.
