Thursday evening saw Lord Sugar set the two teams their latest challenge which involved selling products at a boat show.
Both teams had to sell a mix of low and high ticket items, ranging from cheap fish pillows and snorkels to jet skis and speedboats worth tens of thousands of pounds.
When it came to the results there was a clear winner with Frances Bishop leading team Nebula to their first victory this year. Frances’ team brought in over £40,000 worth of sales while Karthik, who as project manager of Team Titans, managed less than £200.
Who left The Apprentice this week?
It was one of The Apprentice's worst results in history and Lord Sugar showed no mercy when it came to PM Karthik.
“Karthik, listen to me, there is no excuse, you have been a diabolical project manager. I don’t even trust you to bring anybody back into this boardroom. Karthik you’re fired!” Lord Sugar declared.
Chatting after his exit, Karthik had a lot to say.
"I really respect Lord Sugar for what he's done," he told DigitalSpy. "We come from different backgrounds but I think we offer the same thing to the business. I take no rubbish from him and he takes no nonsense from me. He's called me a loose cannon, I'll call him an old fart… no offence intended!"
Karthik continued: "I do respect him for what he's done. I look at him as a rough diamond. He's a diamond but he is a little bit rough around the edges. It is what it is, it's his background, the way he speaks, the way he behaves, and that's okay, I respect him as a tribal elder, if you like, and I'm like the warrior."
Karthik went on to claim that Lord Sugar fired him "on the basis of emotion rather than logic" after he wouldn't keep hushed in the boardroom.
"I think he liked me and he respects my skills, so if I had instead just kept quiet and if I'd sat back, I have a feeling that I just might have stayed on," Karthik said.
