Karren Brady has described tonights task on The Apprentice 2013 as the worst she's seen.
In the latest challenge for the two teams and the 15 remaining candidates get a 6am wake-up call, asking them to meet Lord Sugar at The Old Bank pub in Fleet Street.
He tells the business wannabes at the top of the episode: "Beer is Britain’s favourite alcoholic drink, with sales totalling £18 billion per year. Now what I want you lot to do is to come up with a new flavoured beer.”
Lord Sugar chooses a project manager for each team according to candidates’ proposed business ideas – Tim wants investment for a new form of drink, so Lord Sugar moves him to the girls’ team to project manage Evolve, while Kurt, who is also in the drinks business, is picked to project manage Endeavour.
Tonight the two rival teams have to produce, brand and sell their own flavoured beer before closing time in the boardroom, but it was a painful task for Karren.
Following the girls, led by Tim, Karren revealed how the candidates struggled with the formula.
"The worst situation I have ever seen comes in the second episode. It's the worst situation not just in the episode, but in my life," she said.
Karren explained: "There is a simple mathematic formula connected to beer. And they couldn't get it right. For hours and hours. It wasn't hard. It was hugely, hugely frustrating."
The Apprentice 2013 airs tonight at 9PM on BBC One.
