Amanda Abbington has told how she has a decades-long bond with her Strictly Come Dancing co-star Layton Williams after working with him in one of his earliest roles. Sherlock star Amanda, 51, and Layton, 29, both had roles in the 2011 CBBC mini-series Postcode about a Somali boy and his family who move to London and are now set to be reunited in the Strictly ballroom. And although Amanda admits to being competitive and having her eye on the Glitterball trophy, she is tipping her old co-star, Bad Education's Layton, for the top spot in this year's BBC series.
