A City fund manager sacked a female director who refused to join him at Kabbalah sessions, a tribunal has heard.

Guy Oppenheim, chief executive of Notz Stucki, one of Europe’s largest asset management firms, allegedly bombarded Nadine Nassar with suggestive, late-night text messages and phone calls.

Last week, Central London Employment Tribunal heard how the married 55-year-old encouraged her to take part in the Kabbalah classes.

She was sacked in April 2007 after turning down his alleged advances and dropping out of the sessions.

Ms Nassar is suing the company, and Mr Oppenheim, for discrimination, sexual harassment, unfair dismissal and victimisation, which they deny.

The case was expected to conclude today.
