The chief financial officer of the horseracing regulator, the IHRB, has resigned a year after embarking on voluntary leave in the wake of the emergence of a financial matter of “grave concern” at the body.

Donal O’Shea has resigned from the Irish Horseracing Regulatory Board "and no longer works for the IHRB”, the board confirmed in a statement.
