From the Diary of the London Evening Standard:
Boris Johnson's policy director Anthony Browne is expected to announce his resignation in just a matter of weeks. The former journalist has his eyes set on Michael Ancram's safe Wiltshire seat of Devizes. Browne's departure will be the latest in a string of City Hall departures following the embarrassing exits of three deputy mayors and two senior advisers.
Interesting story. Can it be true? Informal inquiries at City Hall produced prompt replies to the effect that the answer was "no". I've since requested a formal response to the Standard's story. Something, you feel, has got to give.
