All it needed was a line underneath saying "and Nick Clegg's the new deputy PM, so any delays on the London Underground are his fault".
Update: The message got removed and according to The Mirror a TfL spokesperson said:
"Our service information boards are in public areas of stations and are used to update our customers of service changes. This message has been removed, we are urgently investigating how it appeared, and apologise for it."
How do they explain all of the other human touches on the service update boards? Does this mean I won't see my daily birthdays & fact of the Day at Kew Gardens any more? What about Mr Warwick Avenue's cheery ones? Maybe there'll be a new TfL rule - no political comments on the noticeboards.
