Boris in power has been true to his core beliefs. He has done everything he can to encourage car use, and binned Ken Livingstone's carbon-reduction plans. He has halved the size of the environment team, scrapped the expansion of the Congestion Charge to west London, postponed indefinitely the expansion of the city's "Low Emission Zones", and cancelled Ken's plans to charge ultra-polluting SUVs an extra £25 a day.
Despite constantly inviting photographers to snap him on his bike, he has hacked £27m out of the budget for building cycle lanes, wrecking proposals for 300 new ones.
The political symbolism is exposed as a sham by the political reality. Other than planting a few trees, his environmental policy has been "totally appalling", according to Darren Johnson, the excellent Green member of the London Assembly.
