Irish riders dominated the Puissance competition on the opening day of the inaugural four-star Liverpool International Horse Show, with county Tyrone’s Peter Smyth receiving a standing ovation when he claimed the top prize.

Smyth cleared the massive red wall at its final height of 2m16 (7ft 1), with Mary McCarthy's Irish Sport Horse, Cavalier Rusticana, while Tipperary’s Shane Breen dislodged a brick at the final attempt with Gotti Van Paemel to finish as runner-up.

Three more Irish riders finished in equal third place, Anthony Condon, Denis Lynch and 17-year-old Christopher Megahey (with the Irish Sport Horse Seapatrick Cruise Cavalier), all reached the fourth round.

In the opening international class event, Shane Breen finished sixth riding Special K, while Waterford’s Anthony Condon took ninth aboard Aristo. Breen also took fifth place in the  Accumulator competition riding Eclips, with Billy Twomey finishing seventh aboard Diaghilev.

County Longford’s Aisling Byrne finished as runner-up in the opening Amateur class of the show, while she also finished second in another Amateur competition, where she was joined on the podium by Ireland’s Lucinda Roche in third.
