The charges related to Kenyon Confronts, a BBC television programme, broadcast in June.

In that Murphy was recorded claiming that �1,600 had been made on the defeat of his horse, Christiansted, at Fakenham in February with bets laid on betting exchanges.

He later insisted the comments had been taken out of context and he would fight the accusations but was still fined �4,000.

With the Jockey Club hearing hanging over him, Murphy, who has more than 100 horses under his control at Wynbury Stables, has still gone on to train 13 winners this season.

The Irishman has been involved with the horse racing fraternity since working for Phonsie O'Brien back in Tipperary as a teenager.

He later left the sport to work on building sites in London but returned as a stable jockey for trainer Paddy Mullins, with whom he worked for five years.

His first major success as a trainer came in 1980 after leaving Mullins' yard to become a freelance trainer.

The horse in question was Anaglogs Daughter, which he coaxed to victory in the Arkle Chase at Cheltenham.

Murphy's first training role in England came at the end of the 1980s when he moved to Worthingworth Hall as Geoff Hubbard's private trainer.

There he enjoyed mixed success, Gee-A as the youngest ever winner over the Grand National fences (in the Foxhunters' Chase) and Sibton Abbey's Hennessy success among his most notable achievements.

He became a private trainer in April 1994 at Oakwood Stables in Middleham before setting up his current yard nearby back in 1998.

Since then he has enjoyed success in the Scottish Grand National (Paris Pike) and at Cheltenham Festival (Paddy's Return, Stop the Waller and French Holly).

And at the 1999 Grand National, his charge Addington Boy came home a creditable fourth.
