Mrs Blair has supported the event since it began six years ago, and while she has been applauded for entering into the spirit of the occasion by wearing tailor-made saris - last night she was in a jewelled lilac shalwar kameez by designer Babs Mayhill - some have criticised her decision to go Asian. Last night, however, it was the duchess's turn. One commentator said that most ag reed her turquoise silk suit with a chiffon shawl was "an appropriately discreet nod towards the spirit of the evening", others were disappointed that she had not followed Mrs Blair's example.
