It was Tom O’Brien at Aintree and Paddy Merrigan at Haydock. I know he really liked that horse, losing the ride on him and Souffleur was one of the things that caused one of his departures.
Off topic, Merrigan could’ve been a top jockey but his temperament was always a little dodgy. He had another comeback in Ireland earlier this year but had a bad fall from Bobs Way in Down Royal on St Patricks Day. The last I heard he had put on weight recovering from injury and was doing some showjumping.
