Jessie Gilbert, 19, from Croydon, south London, fell from the window of a hotel where she was staying during the Czech Open tournament.

Her father, Ian Gilbert, 48, is to stand trial on seven counts of rape and two of indecent assault. He is due before Guildford Crown Court on 24 August.

Czech police are continuing to investigate how Ms Gilbert came to fall from her eighth floor window in the town of Pardubice on Wednesday.

One suggestion was that she may have been sleepwalking.

John Saunders, editor of British Chess magazine, said he had been approached independently by several chess players claiming Ms Gilbert had a problem with sleepwalking.

Jan Mazuch, director of the Czech Open, said a one-minute silence was held. Some English players had been too distraught to compete and had travelled home. "It is a great tragedy for all of us. Everybody is shocked, " he said.

In a statement issued on Friday, her family described her as much loved and an exceptionally talented chess player.

MsGilbert had been working towards becoming a women's international master chess player and had a place to study medicine at Oxford University.

A former pupil at Croydon High School, she had been taking part in the competition on a year off from her studies.

The English Chess Federation described Ms Gilbert as one of the country's leading women players.
