The former chief executive of Moy Park, Janet McCollum, and the current head of customer support, David Mark, can expect some probing questions at the Renewable Heat Incentive (RHI) inquiry tomorrow (Friday).It comes after last week’s evidence from the chair of the Moy Park growers’ committee, Tom Forgrave, where he was questioned in detail on the role Moy Park played in encouraging their suppliers into the scheme, and the contract between growers and the company. His evidence pointed to Moy Park being a significant indirect beneficiary of the failed RHI scheme.
