Diary: Turkey of the week - Publicis/Asda

Emma Barns is unimpressed with Sharon Osbourne's debut in the new Asda ad by Publicis: "The idea of a multi-millionairess, caked in make-up and dressed in a suit, hardly seems to epitomise the Asda mum. As she wafts around an unusually empty store, piling her trolley with DVDs and children's clothes, you'd be forgiven for thinking her enthusiasm is due to never having shopped in a supermarket before. And she doesn't even slap her own backside ... well, clearly she's not in need of pocketing the Asda difference."
