He gained his nickname of “the Sprint King” with victories in several of the sport's major Group 1 races and repeat victories in top handicap races including six wins in the Ayr Gold Cup, three in the Stewards' Cup and four in the Epsom Dash.
His final winner was Sovereign Debt in 2017 and he retired from training shortly after citing financial problems.
