Roland Paoletti's Jubilee Line extension will form the core of the British exhibition at next year's Venice Biennale, to be developed by the British Council, the Royal Academy and the Wordsearch consultancy. The theme of regeneration will fit well with the subject set by Biennale director Massimiliano Fuksas (seen recently in London judging an Architectural Review competition): 'Cities: less aesthetics, more ethics'. By the way . . . the British Council, chaired by barrister Baroness Kennedy, has a new deputy chair: Peter Mandelson.
