McCusker holds the license to run Cashjumping in Ireland and hosted the first event at his venue two weeks ago. McCusker has sent two solicitor’s letters to Showjumping Ireland and its chairman, Tony Hurley, over comments made in the Irish Examiner last week.

In the letters, Mr McCusker said it was “highly unsatisfactory” that he had learned of SJI concerns about Cashjumping through the press.
