Shop doors - prospective London mayors agree, but powerless

I wrote my concern about the unnecessary damage of open shop doors to the three main candidates for London Mayor. Brian Paddick answered first (by email) saying that he agreed, but such legislation was not in the Mayor's power. Then answered Ken Livingstone's office, saying also that such legislation was not in the Mayor's power. Finally, I received a letter from Boris Johnson's office, with a vague agreement that London should become greener.

We now have a new London Mayor; let us see.
