Sadler's Wells chief executive Jean-Luc Choplin has resigned from the venue to take a post at Paris' Chatelet Theatre.
Mr Choplin will leave in 2006
Mt Choplin, who joined the London dance theatre in 2002, will leave in 2006.
His announcement comes after allegations of sexual discrimination against the French chief executive made by three former managers.
But a Sadler's Wells spokesman said Mr Choplin's departure was not connected as the cases had been settled amicably last year.
Three of the managers alleged they were unfairly dismissed by the new chief, while a fourth left of her own accord but said she had been the victim of constructive dismissal.
"While naturally disappointed to be losing someone of Jean-Luc's talent in 2006, we recognise the attraction for him of joining one of the oldest and most famous theatres in France," said Sadler's Wells chair Denise Kingsmill.
