RACING: Stephen Scott, the producer of the BBC Panorama investigation into alleged corruption in racing which was broadcast on Sunday night, has said he may make a second programme, using additional material supplied to him by Roger Buffham, the Jockey Club's former head of security, and information received since.

"The phones ring as they do when these sort of allegations are made," Scott told Radio Five Live. "I'm at the moment looking at some quite serious allegations about a leading bookmaker, and there are other stories about a couple of Jockey Club members that we've been informed about. What we've done is only the tip of the iceberg."

The news that Panorama might continue to investigate the racing industry will not have been welcome at the Jockey Club's headquarters, where damage limitation was underway yesterday. However, it was tempered by a statement from Richard Caborn MP, the British Sports Minister, in which he said that the club had his "full support" in its attempts to regulate racing.

"Our plans for the reform of gambling law include proposals to establish a new gambling commission," Caborn said, "which would be responsible for licensing and regulating bookmaking alongside other forms of gambling, and which would have powers to exchange information and otherwise co-operate with the Jockey Club as racing's regulatory body.

"The club has worked very hard in recent years to maintain the integrity of racing both as a sport and as a betting product, and punters can have a good measure of confidence."

At the club's head office in Portman Square yesterday, Jeremy Phipps, the current head of security, was resisting calls for his resignation, and, according to John Maxse, the club's spokesman, "working as normally as possible on a day like this".

Phipps was secretly recorded by Panorama in conversation with Buffham, his predecessor at Portman Square, claiming that the sport's regulators lacked the "backbone" to do their job properly.

Christoper Spence, the senior steward of the Jockey Club, refused to cut short a holiday in Greece to return home for Sunday night's long-awaited investigation. However, yesterday he issued a statement in which he described the programme as "flawed".

"Although skilfully put together, in my view the programme was flawed as a result of its over reliance on discredited witnesses with their own agendas," Spence said.

Buffham, Panorama's principal source, left his job last year following an inquiry into alleged "gross misconduct", while another significant interviewee was Dermot Browne, a former jockey and trainer, who was banned from racing almost 10 years ago.

"Furthermore," Spence said, "it was not made clear enough to the viewers that much of the material analysed related to incidents which took place between five and 15 years ago, well before many new measures were introduced to protect racing's integrity and deter corruption."

Jockey Frankie Dettori said yesterday he thought the investigation was "absolute rubbish". "Nothing new came out," Dettori told reporters. "I have been all over the world and the Jockey Club in England has probably the best, most policed sport in the world."
