Gavron worked on the mayor's London plan, which proposes a series of clusters of tall building in the capital. Gavron hinted that Livingstone wanted to go further, and build high-density towers in other parts of London.
She said: "We've got to be careful not to open a Pandora's Box of high-rise and say that it can go anywhere."
It also emerged that Gavron had wanted to include the regeneration impact of an Olympic bid in the plan. However, Livingstone told her not to take account of the bid, as the government had yet not committed itself to it.
