Darren Williams met Miles Rodgers (front) at the pub

Mr Williams's home was raided the next day and police found a white envelope under his mattress, jurors were told.

Mr Williams had lost a race on the previous day, winning Mr Rodgers �16,556, prosecutors added.

Six defendants including Mr Williams and Mr Rodgers deny conspiracy to defraud customers of Betfair.

Detective Constable Steve Woods told jurors that he saw Mr Rodgers, Mr Williams and Karl Burke, a trainer, at a table at the Bridge Inn, Walshford, North Yorkshire, in July, 2004.

Sitting nearby, he heard the words "Great Yarmouth", "seven lengths" and "seventy-seven grand", he told the court.

Mr Woods said: "They all left together. In the car park, I observed that Williams had a white envelope in his left hand."

The six defendants deny conspiring with others between December 2002 and September 2004 to defraud online betting exchange Betfair customers and other punters by plotting to fix 27 races.
