Cork businessman Leslie Buckley (74) had a challenging year in 2018, stepping down from his role of chairman of the board of INM in May as a scandal about alleged data breaches unfolded at the newspaper group. He subsequently welcomed the appointment of High Court inspectors to the company as an opportunity to 'vindicate' himself. He originally made his name as a restructuring expert working with companies such as Waterford Crystal, Irish Steel and Aer Lingus. A close associate of Denis O'Brien, he was chief operations officer of Esat Telecom from 1996 to 1997. He is estimated to have made €10m from the sale of Esat to BT in 2000 and €70m from his interests in Digicel. Buckley and his wife Carmel co-founded Haven, a housing and sanitation charity in Haiti.
