The G2 section of the Guardian has an interesting assessment of Boris' mayoralty so far:
"Johnson may need a lot of help. Even now, his popularity as mayor could be more apparent than real: astonishingly it has yet to be measured in an opinion poll. And Londoners can quickly tire of their leaders. Just off Tottenham Court Road in the centre of the city, there is a faded mural. It is a rather bleak panorama of London life, painted in 1980: traffic, cranes, dark pubs, grey-faced people. High up in the picture, presiding over the near-chaos, is a flamboyant Tory politician who has been viciously caricatured, as a red-eyed, bow-tied vampire. It is Horace Cutler, the Boris Johnson of his day.
Cutler's administration took office in 1977, governed London with flair, and then ran into a recession and a country-wide revolt against the Conservatives. The year after the mural went up, the Cutler regime was voted out. He soon left politics to pursue other interests."
