Sky1 HD has called upon the expertise of retail consultant Karl McKeever for its documentary series 'Body Language Secrets'.

In the episode 'Selling', Karl, a brand director at Leicestershire based visual merchandising consultancy Visual Thinking, takes former Big Brother psychologist Anjula Mutanda down Carnaby Street in Central London to introduce her to the techniques used by retailers to encourage customers to buy.

Other episodes in the eight part series made for Sky1 HD by Carbon Media, will deal with the themes of attraction, power, lying, money, humour, winning and sex. The series aims to help viewers understand the way they and others think and behave to help improve the quality of their everyday lives.  

This isn't the first time Karl has appeared on national TV - as an expert in his field who advises the likes of M&S, Matalan and Sainsbury's, Karl frequently contributes to national news articles on retail, and has appeared on TV shows such as 'Shopping the Supermarkets'.
