TV critics branded it the bust-up of the series when Sydenham’s Bianca Miller fell out with fellow contestant James Hill in spectacular fashion on last night’s The Apprentice.

Bianca, 25, found herself at loggerheads with gobby teammate James, who was in charge of Team Summit for this week’s board game task.

"Every opportunity, there's been times today when you've been difficult - it's as if you've been very big for your boots," blasted James.

"You've sat there with smirks on your face, you're picking on little things and you turn it into a problem - and I'm not having it."

But business owner Bianca, who went to Sydenham High School before attending the University of Sussex to study Business Management and Economics, fought back.

She said: "I will speak when I need to speak. I will not be restricted by him.

"As the saying goes, a wise man speaks because he has something to say, a fool speaks because he has to say something.

“I’m not saying he’s a fool but he likes speaking a lot.”

Bianca and James made it through to the next week's New York special after their geography-themed game GeoKnow, brainchild of accountant Roisin Hogan, chalked up £2,080 in sales.

Lord Sugar criticised Bianca for offering a small shop exclusive rights to stock the board game in the whole of Westminster in exchange for selling just six boxes.

Project manager for Team Tenacity Pamela Uddin, 22, became the tenth candidate to be fired after her relationship board game was branded “sexist” and “offensive”.
