Guy Harrison is a millionaire entrepreneur who lives in a sprawling farmhouse and spends his spare time pursuing extreme sports.

But his thrill-seeking lifestyle belies a hidden pain. His relationship with the mother of his child broke down because he refused to marry her.

Friends say eccentric Mr Harrison has not seen his five-year-old daughter for two years.

His ex-girlfriend has since married another man and friends say he is desperate to see his daughter.

Mr Harrison, 36, is co-owner and a non-executive director of Datography, a Putney-based company which provides floor plans and virtual tours for estate agents.

Datography managing director Rupert Fisher said "The last time Guy saw his little girl was two years ago under supervised conditions. He can't speak to her or see her any more.

"He also sends her presents and they get returned to him.

"He would do anything to see his daughter, who he has nicknamed Whizz."
