In 2018 and 2019 he won the Grand National with Tiger Roll, ridden by Davy Russell and owned by Gigginstown House Stud, the first horse since Red Rum to win the race twice.
In March 2021 the Irish Horseracing Regulatory Board imposed a twelve-month ban (with six months suspended) on Elliott after a photograph surfaced of him sitting on a dead horse on his gallops in 2019.
[1] The son of a panel-beater, he grew up in Summerhill, County Meath and entered the racing world at the age of thirteen, working for trainer Tony Martin at weekends and holidays.
[2] Although best known for his victories over jumps, Elliott had a major win on the flat in August 2010 when Dirar won the Ebor Handicap at York Racecourse.
[11] That year he also won the Aintree Grand National with his horse Tiger Roll, ridden by Davy Russell and owned by Michael O'Leary's Gigginstown House Stud, narrowly beating the Willie Mullins runner Pleasant Company.
[12] On 28 February 2021, the Irish Horseracing Regulatory Board (IHRB) launched an investigation into an image of Elliott, which was widely circulated on social media, sitting on a dead horse and making a peace sign.
[17] Minister of State for Sport Jack Chambers said that Elliott must be "held fully accountable for his actions" and that the photograph showed "a complete and profound error of judgement".
[18] On 2 March Cheveley Park Stud announced that they would move their horses – Envoi Allen and Quilixios to go to Henry de Bromhead and Sir Gerhard to go to Willie Mullins.
[18] Elliott's leading owners, Michael and Eddie O'Leary through their Gigginstown House Stud, expressed their support for him despite being "deeply disappointed by the unacceptable photo".
[21] In July 2021, Elliott featured in a BBC Panorama programme that investigated the fate of British and Irish racehorses who end up in abattoirs.
[23] The latter horse, owned by Simon Munir and Isaac Souede, was grey gelding Vyta Du Roc, who won the 2016 Reynoldstown Novices' Chase.
