The British Horseracing Authority has refused to comment on new allegations of race-fixing.

A report in the Sun this morning claims that five jockeys are currently under investigation for riding horses to lose over a period that could stretch back as far as six years.

Paul Struthers, head of communications for the BHA, said: ‘We have a team of investigators who each have a number of ongoing investigations into a variety of matters at any one time.

‘It would be inappropriate to comment on individual investigations except those that are already in the public domain or until such time as an investigation has been concluded and charges issued.’
