Aga Khan Irish role for Murtagh
Johnny Murtagh has been retained to ride all of the Aga Khan's Irish-trained horses in 2011.
The jockey resigned from his post as stable jockey to Coolmore last week and has quickly been snapped up by the leading owner.
"I am thrilled to be renewing my association with His Highness' horses in Ireland," Murtagh said in a statement.
"We have shared some fantastic moments over the years and I have always enjoyed riding in the green and red colours.
"This will also give me an opportunity to ride for John Oxx again.
"I started off riding for Mr Oxx and it has always been a pleasure to be part of his Currabeg team."

Murtagh was stable jockey to Oxx from 1992-2003, during which time he rode 18 Group One winners for the Aga Khan.
The jockey was on board Sinndar when he won the Epsom Derby, the Irish Derby and the Prix de l'Arc de Triomphe in 2000, while he also partnered the likes of Alamshar, Kalanisi and Daliapour to big-race successes.
"I am delighted to have secured a world-class jockey like Johnny Murtagh as my retained rider in Ireland," said the Aga Khan.
"We have had some wonderful days in the past and we look forward to renewing our successful association.
"I believe it is vital to the continued success of my bloodstock operation to have a retained jockey in the countries where my horses are trained.
"This has been the situation in France for many years and I am most pleased now to have a similar arrangement in Ireland."
Murtagh's victory on Recital in Saturday's Criterium de Saint-Cloud looks likely to be Murtagh's final success as retained jockey for the Coolmore operation.
