UK raiders Tax Free and Reverence cut out the running and looked to have the Listed contest between them heading down to the final furlong over the minimum trip.

Charlotte Bronte (9-10) completed a fantastic day for Murtagh when repelling the challenge of Tobar Na Hinfe in the goracingatnaasracecourse.com Maiden.
