Twyford trainer Alan Jarvis plans to appeal against the British Horseracing Authority’s decision to reject his request for a full licence, which could signal the end of his career.

The 75-year-old was said to be “deeply disappointed” after the BHA’s licensing committee made the announcement on Tuesday, although he will be allowed to operate on a temporary licence until April 25.

A BHA statement said the licensing committee had determined that Jarvis was not a suitable person to hold a licence, with the reasons for its decision to be released in due course.

However, it comes after he was declared bankrupt last September over a debt owed to Doncaster Bloodstock Sales Limited, which is reported to amount to several hundred thousand pounds.

The order was issued by Aylesbury County Court, and the matter relates to a number of yearlings that Jarvis bought at the sales in 2005.

However, Jarvis plans to contest the decision, with the BHA confirming he has seven days in which to lodge his appeal.

A statement issued on the trainer’s behalf by barrister Roderick Moore read: “Mr Jarvis is deeply disappointed that the licensing committee has seen fit to remove his licence after many decades of successful training.

“Unless the decision is overturned on appeal, it will be catastrophic for him and his family and all those that work at Mill Race Stables.

“He intends to appeal.

“He does not intend to make further comment until his appeal is heard. In the meantime, he has been granted a temporary licence pending appeal.”

Jarvis, whose training career began in 1969, has saddled more than 750 winners.

His best-known horses incl-ude Derring Rose, Hill Of Slane, Kildimo, Jardines Lookout and Navajo Chief, who is among his current string of 33 horses, which also includes Lady Lara, who is entered in the Qipco 1000 Guineas.

He has been based at Twy-ford since 2004, having trained at Aston Upthorpe near Didcot.
