Boris Johnson's Empty Promises

Boris Johnson has produced a policy document full of ambitions that he presumably hopes someone else will achieve.  During his five years as Mayor, he has managed lots of words, but actually activity has been allowed to run into the sand.  House building has reached a nadir.  Transport investment is under threat.  Police numbers are being cut.  At least on air quality has now done a screeching u-turn although I suspect only because he is afraid of an EU fine.  Meanwhile, the city has been entertained with various vanity projects, of which the new routemaster is the most prominent.  It is a warning that whoever succeeds him needs to have skills others than those needed for generating publicity.
