I have just driven along the Embankment between Westminster Bridge and
Temple and just about every lamp post on both sides of the road is
bearing a vertical hanging banner stating "I am a Londoner", followed
by "Mayor of London" and "British Gas".

Does anyone know what the purpose of this latest inanity is?

If it was, for example, the President of Iran proclaiming "I am a
Londoner", in Kennedyesque (Ich bin ein Berliner) solidarity against
terrorist bombers I would understand and condone the sentiment, even if
it was a total waste of money.

But what is the point of this latest gimmick. Anyone any ideas?
