According to Councillor Danny Chalkley, cabinet member for transport and economic development, the Council
‘bought the copyright as we felt we needed to retain an element of control over the signs to maintain Westminster’s image as a world class tourist information.’
The IPKat isn’t sure about this one. Surely much of the value comes from the names themselves (which won’t be protected), rather than the format in which they’re presented. Moreover, the Kat can’t really see how it’s helpful to the tourist industry to crack down on souvenir sellers, which presumably is the eventual aim. The Kat guesses that the Council thinks it’s on to a nice little earner of ‘official’ Westminster merchandise.
