It is a little-known fact of British political life, and one of those "Official Secrets" that tourists are not supposed to know, but every Prime Minister is allowed his (or, indeed, her) personal bus stop on the corner of Parliament Street and Parliament Square.
We were fortunate enough at the beginning of June to witness the transition.
Tony's bus stop was there in its full glory.
When we passed, the creation of Gordon Brown's was work-in-progress
The Mayor, of course, gets two Tube Stations for his own personal use.
If I suddenly stop blogging, assume I have been marched off to the Tower for divulging this Top Secret information
