The site does not make it clear whether Kara Tointon is included in the prize....
From the BBC:
Is it any wonder that Dawn caught Rob's eye in this quality clobber? Here's your chance to own a Dawn Swann signature piece - her pretty pink top. To enter, just answer the question below. Three runners-up will win fancards signed by Kara Tointon
When did Dawn's mum move out of Walford? http://www.bbc.co.uk/eastenders/competitions/
If you don't live with a rabid Eastenders fan (which unfortunately I do...) the answer can be found by clicking the link on the entry page
