The team dynamics in the early episodes of the series are always glorious – a classic school-disco boys vs. girls set-up sees the former all blatantly trying to out-do each other by measuring up their, um, ‘business credentials’, and the latter preaching “girl power!” to each other’s faces before sniping as soon as backs are turned. In a shock twist, this series will mix up the teams for the first time – but expect all that backstabbing to remain intact.
