Nichols renews attack on Exchanges Racing´s governing body yesterday resumed its attack on betting exchanges, calling for them to be properly regulated and to contribute more to racing.At the British Horseracing Board´s annual general meeting, chief executive Greg Nichols used his speech to get across the message that they are very worried by the integrity issues of people laying horses to lose on exchanges and said the 'scale of this threat is unprecedented´´.He said: 'It is fair to say that betting exchanges have provoked outrage internationally, with major horseracing jurisdictions, most notably Hong Kong, Australia, the US and France, strongly asserting that exchanges represent a significant threat to the sport´s integrity.'The damage that could be created by a betting exchange market operating without appropriate regulation was evident in many recent media headlines - inevitably reducing public confidence in integrity, the foundation of our great industry.'Whatever potential problems existed in the past, there is no doubt in my mind that the scale of this threat is unprecedented.'BHB, while acknowledging the undoubted popularity of exchanges, has long held the view that they must be subject to proper regulation. 'Racing requires support in order to maintain public backing for the sport and we ask the Department of Culture, Media and Sport and others in government to recognise this and take the appropriate steps.´´
