Not that it has any more reevance than a good many of the other posts in this thread...but I recall that Southend renamed themselves London-Southed in the AIP a few years ago. The CAA took a rather dim view - demonstrating a surprisingly good grasp of geography - saying that they were nowhere near London and that they couldn't change the name.
The airport still calls itself London-Southend, and that's the company name too - but in the AIP it's still plain old Southend (in so many ways).
And I doon't think there was much of an airspace grab after that little episode.....
