A woman who worked as a secretary for Prince Charles' (searchroyal staff has filed a complaint alleging sex discrimination and unfair dismissal.

Elaine Day worked as a personal assistant during her five years in employment at Clarence House (search), Prince Charles' London residence, before she left earlier this year.

Paddy Harverson, communications secretary to the Prince of Wales, said Tuesday that Day's claim was filed at Croydon Employment Tribunal.

"The former employee has filed a complaint alleging unfair dismissal, sex discrimination and victimization on the grounds of sex," he said. "We will be contesting the complaint vigorously."

The Employment Tribunal said Day's complaint was filed last week. Prince Charles' staff have about three weeks to respond to it, and a hearing has not been scheduled yet, it said.
