London's City Corporation is preparing a first in consultation - it is taking its Unitary Development Plan, already out for consultation, to mipim, the big property show in Cannes, to allow the international community to have its say. Expect this to set a trend. 'We have stolen a march on Frankfurt,' says Judith Mayhew, chairman of the corporation's policy and resources committee. 'They always do next year what we do the previous year.' Of course the City should really be worrying about Berlin.
