Sienna Miller cover of GQ (UK) wins reader's choice poll as best cover of 2009.

This was the best British magazine front cover from last year, as voted by the public in the annual Maggies magazine cover awards. (thanks to Magculture.com). The Maggies are the result of a national poll of readers.

The Maggies website  quotes Charlotte Zamani, the managing editor, on why it was the winner:

At a time when ‘flat was the new up’, GQ grew by 8% at UK newsstand and now outsells the main competitor by 2-1, making it the pre-eminent title in the luxury men’s lifestyle sector and taking home 45 per cent of the men’s lifestyle advertising. Sienna Miller remained true to GQ by epitomising our winning strength of character with headline-grabbing stories. We made her one of our best-selling covers of 2009, a year best forgotten for some, maybe, but another memorably successful one for GQ.
