taking the Trainers Championship in 2015/16. Owners Aristocratic families have always owned horses in Britain and the list of Classic winners features names such as the Earl of Grafton, Earl Grosvenor and Earl of Egremont from early days. In the modern era, the Queen continues to retain a stable of horses trained by the likes of Michael Stoute. The Queen Mother was famously keen on horse racing and a race at the Cheltenham Festival, the Queen Mother Champion Chase, is named in her honour. The two most prominent flat owners of the current era are Sheikh Mohammed, under the Godolphin banner and the team of Michael Tabor, John Magnier and others, based in Ireland.
