Luke Comer, the billionaire co-founder of Comer Group, one of Britain and Ireland’s largest property developers, has had his trainer’s licence suspended for three years by the Irish Horseracing Regulatory Board (IHRB) after 12 of his horses tested positive for anabolic steroids in October and November 2021.
Comer was found to be in breach of Ireland’s anti-doping rules after a nine-day hearing in front of the IHRB’s referrals committee in May, details of which emerged on Thursday.
