Could Boris block the tower block?

It's well worth reading two stories from yesterday's Evening Standard: The towers that Boris could stop being built and Comment: credit crunch will dictate skyline. These explain that Boris is embracing the powers to veto planning permission that Ken gave himself, but intends to use them to overturn planned tower blocks all over London.
The interesting thing is that many of the 14 developments the Standard picks out as likely to be axed are barely taller than the ones we're facing in Walthamstow, on the Arcade site and at Blackhorse Lane. Could we be numbers 15 and 16?!
We're contacting Boris, and his new planning adviser Sir Simon Milton. And we'll let you know how we get on...
