The England and Wales Cricket Board, who have led the campaign to rid cricket of match-fixing, have sealed a deal to cash in on the forthcoming Test series against Pakistan.

Internet bookies Blue Square, who will be featured on the official Lord's website, will give the ECB £10 for every new punter who places a bet on the first Test in Lahore, which starts on Wednesday.

For every gambler who places a further 10 bets with the bookmaking firm, they will also give the ECB £10 - opening up the possibility of a lucrative reward for English cricket.

But despite the stance of ECB chairman Lord MacLaurin, who has actively campaigned to rid cricket of all forms of corruption and called for life bans on any player or official found guilty of those offences, the ECB have seized on the opportunity to raise extra funds.

"There are betting tents at all the major Test match grounds during the summer in England and the only restrictions that apply are to officials and players - there's nothing which says a cricket fan cannot have a bet," said an ECB spokesman today, who pointed out Blue Square advertised on perimeter boards at Test grounds all last summer.

Former England captain Alec Stewart, who had denied accepting money from a bookmaker in return for information during the tour to India seven years ago, has also revealed he is ready to undertake anything which is asked of him by the International Cricket Council's anti-corruption unit - even if that means taking a lie-detector test.

The ACU, headed by former Scotland Yard chief Sir Paul Condon, have begun their inquiry into allegations contained in India's Central Bureau of Investigation into corruption which includes the names of Stewart, Brian Lara and seven other former Test captains.

They have returned from visits to India and South Africa and intend to "undertake the extremely detailed and complex investigations needed to test these allegations."

Stewart said: "I've only ever seen lie-detectors on movies and television and I don't know if they're 100% fool-proof, but Paul Condon has a great track record and there's no reason why I should doubt any of his methods.

"I expect at some stage I will be asked to go and see Paul Condon for a chat or an interview and I will be co-operating fully with the investigation."
