Lord Sugar said in a statement that Stella English's claim was "a derisory attempt to smear [his] name" and her reputation "is now in tatters".
I am pleased that the tribunal has returned this verdict and feel vindicated in the judgment that myself, my companies, the BBC, the TV production company and my staff acted properly throughout Ms. English's employment.
There was never a case for us to answer but her need for money and fame meant that the whole system was subjected to this charade.
I have been cleared of a derisory attempt to smear my name and extract money from me.
The allegations were without substance, and I believe this case was brought with one intention in mind - the presumption that I would not attend the tribunal, that I would not testify and that I would settle out-of-court, sending Ms. English on her way with a tidy settlement.
I'm afraid she underestimated me and her reputation is now in tatters. I have principles and I am not going to be forced to compromise them, no matter how much time and money they might cost me.
Entrepreneur Lord Sugar has accused a former winner of his TV series The Apprentice of being a liar and attempting to blackmail him.
The 2010 Apprentice winner said she was just an "overpaid lackey" in the job she was given by Lord Sugar, an employment tribunal heard.
