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.
The Tribunal case brought by Stella English against me and my company has been dismissed. A victory for the law against the claim culture.

Lord Sugar said he feels "wronged" by a former winner of the Apprentice who is currently suing him for constructive dismissal, an employment tribunal heard today.
Stella English, 34, from Whitstable, Kent, claims she was treated as an "overpaid lackey" after winning series six of the BBC1 programme.
Giving legal submissions today, Lord Sugar's representative Seamus Sweeney said: "The claimant has, in the eyes of Lord Sugar, deliberately courted the media with a view of damaging his reputation."
He told how Ms English had "sold her story" to the press several times and accused her of being a "headline-grabber", deliberately sensationalising aspects of her evidence.
He told the tribunal the same was true of Ms English, adding: "Using the media, in this case, was a weapon of choice... It was a first weapon of choice."

Lord Sugar said nothing as he left an employment tribunal in which the 2010 winner of his TV series The Apprentice is trying to sue him for constructive dismissal.
In an exchange with Philippa Jackson, representing Stella English at employment tribunal, Lord Sugar accused his former employee of lying about her version of events to generate publicity.
When Ms Jackson suggested he appeared angry, he said: "I'm angry because of this, because it's a total lie".
"When I came into the process of this tribunal, I was going to try to be generous to your client, but I've sat here and listened to her over the past two days and there is no other way to describe what she has said than as blunt lies."
