Talks between trainer Patrick Biancone and chief stipendiary steward Bernard Hargreaves look certain to lead to the Frenchman having no runners at Happy Valley next Wednesday night. Biancone has eight horses entered - most of them on the reserve lists of the seven races - but current arrangements in relation to his horses are placing great pressure on several Jockey Club departments. Biancone has spoken to Hargreaves and a final decision on not to declare his horses is likely to be taken today. Said Hargreaves: 'It is really up to Patrick but we have spoken about it and a breathing space would hurt no one. He is apparently not desperately keen to run anything anyway.' Biancone, who has had 24 horses return positive to Dembrexine, confirmed that he was unlikely to have any runners at the Valley meeting. Under a Board of Inquiry instruction, all Biancone's intended runners have to be specially checked for prohibited substances and they are also being held in very tight security. His runners for the Martell Gold Cup and Grand National meeting at Sha Tin tomorrow are virtually under 24-hour guard. In further developments, all bedding in Biancone's stable has been painstakingly removed and placed in a separate building. The bedding is being thoroughly tested for Sputolosin, the trade name for the generic drug Dembrexine, to see if any of the horses could have ingested the substance in that manner.
