Cornelius Horan was led away by security guards in Athens

Leslie Broad, of Deunant Books in Denbigh, north Wales, said he would do his utmost to ensure that Cornelius Horan's royalties went to charity.

Former Catholic priest Mr Horan was given a 12-month suspended sentence after ambushing the front-runner.

Mr Broad, who publishes Mr Horan's religious books on the web, called him "a damned fool".

He said he was in talks with lawyers over the contract Mr Horan had signed with his company, to see whether there was a get-out clause.

"The man is a damned fool," he said.

"I will do everything in my power to ensure that any royalties from books sold as a result of his actions will go to a charity, rather than to him.

"I will talk to him myself before I send him his royalty cheque and do everything I can to persuade him that he should give his money away to charity. There is no way that he should profit from this."

Mr Broad - who set up his e-books website 18 months ago - said he was shocked when he heard that Mr Horan had pushed Brazil's Vanderlei de Lima off the road.

De Lima was about four miles from the end, but lost the lead after the ambush and finished with a bronze medal.

The International Olympic Committee also awarded de Lima the Pierre de Coubertin Medal to recognise his "exceptional demonstration of fair play and Olympic values", but refused Brazil's request to change the result.

Since the incident, Mr Broad has been on the receiving end of many angry e-mails from Brazil.

"Some have been well argued, but others have been very deeply offensive indeed," he said.

Mr Horan, aged 57, also ran on to the track at the 2003 British Grand Prix wearing a tam-o'shanter and kilt and carrying religious-themed placards and was given a two-month jail sentence for aggravated trespass.

The other effect of his latest stunt has been that Mr Horan's works have seen a rise in sales.

"It's an unfortunate by-product," Mr Broad said.

"About 80% of the sales have been in America," Mr Broad said. "They have been coast to coast - from New York across to Los Angeles.

"You can't really gloat about sales when they have been achieved as a result of such disgraceful publicity."

Mr Broad said his company became involved with Horan over a year ago, when he approached Deunant Books to take on his biblical prophesy works.

"I have spoken to him scores of times, and I have always got on with him very well," he said.
