Mr Lowe also denies unfair constructive dismissal
A multi-millionaire financier has denied allegations that he hired a hitman to kill a City executive.
Jordan Wimmer, 29, of Chelsea, west London, who earned £577,000 a year, told an employment tribunal she thought her boss Mark Lowe wanted to kill her.
Ms Wimmer, who worked at Nomos Capital, accused Mr Lowe of humiliating her.
Mr Lowe accepted that he did refer to Ms Wimmer as a "dumb blonde" but said the comment was a joke. He denies sex and disability discrimination.
At the Central London Employment Tribunal, Elizabeth Melville, for Mr Lowe, asked her client: "Did you arrange, either through your family or other contacts, to have the claimant hurt or killed?"
Mr Lowe replied: "No."
Previously, medical notes read aloud in the hearing revealed that Ms Wimmer thought a man who looked like Mr Lowe drove a car at her.
She also called police after being followed by a man in May this year.
Mr Lowe, the sole shareholder in the hedge fund firm Nomos Capital, denied ever trying to hurt Ms Wimmer.
The tribunal heard Mr Lowe, who now lives in Switzerland, circulated a joke about "blondes" shortly after Ms Wimmer had received treatment for depression.
Asked what thought he gave to Ms Wimmer when circulating the joke, Mr Lowe said he did not imagine anyone would take exception to the "feeble" joke.
Mr Lowe also denied bringing two high class prostitutes - Russian student Natalia Malagina and a woman known only as Ling - to work events.
Jordan Wimmer was dismissed from her job in February 2009
Ms Wimmer's barrister Julian Wilson said: "Ms Wimmer felt humiliated when you brought Ling dressed provocatively to meetings.
"You brought Ling along, just as you brought Natalia along, to give you status."
Although Mr Lowe admitted viewing the website of a Swiss escort agency, he said it was only for "innocent voyeurism".
He said payments made to Ms Malagina were to "sponsor" her to take an internship in New York.
Mr Lowe said the former stripper and escort was interested in the hedge fund industry and denied claims the money was in return for "favours".
Ms Wimmer was dismissed in February 2009. She is also claiming unlawful deduction of wages, unfair constructive dismissal and disability discrimination. Mr Lowe is contesting all the claims.
