Graham Bradley and trainer Brendan Powell face BHA charges
Former top jockey Graham Bradley and trainer Brendan Powell are to face a British Horseracing Authority (BHA) disciplinary hearing.
The charges allege Powell ran horses in his name when they were trained by Bradley, who is not a licensed trainer.
Bradley was banned from racing for five years until 2007 after he admitted passing on inside information.
He submitted an application, which has yet to be considered, for a training licence in May 2013.
The BHA says it will not release the names of the horses involved or the races in which they ran until after the case has concluded. A date for the hearing has yet to be fixed.
Both Bradley, who won the 1983 Cheltenham Gold Cup on Bregawn, and Powell - who triumphed in the 1988 Grand National with Rhyme 'n Reason - were successful jockeys.
Powell is now based in Upper Lambourn, Berkshire, where he trains horses on the Flat and over the jumps.
Cornelius Lysaght analysis
"Graham Bradley - universally 'Brad' - was an outstanding and charismatic jump jockey, but controversy has long followed closely behind him.
"There was big-race success on star names like Bregawn, Wayward Lad (the title of his revealing autobiography) and Collier Bay, but also brushes with authority.
"After his ban ended, and having taken the requisite courses, there was some puzzlement why the BHA wouldn't give a definitive answer to him receiving a licence to train.
"The charges against Bradley and Brendan Powell would appear to explain that delay. "
