It is week five, and the candidates boldly enter the world of fashion. Lord Sugar ups the ante when he challenges the teams to open pop-up shops at the Trafford Centre in Manchester - one of Europe's largest shopping centres. The teams must select ranges of clothing from some of London's most up-and-coming designers, and are tasked with charming the fashionistas to allow them to represent their brand at retail. Under the ever-watchful eyes of Nick and Karren, the teams swap their business suits for some cool clobber and use every trick in the book to market and promote their stores. In the boardroom, one candidate on the losing team faces a serious dressing-down from Lord Sugar, who is in an unforgiving mood.
