Foster tells inquiry advisers did not tell her of RHI cost increases
Arlene Foster has told an inquiry that she was not aware the RHI scheme was £200m more expensive than an alternative scheme that she rejected.
The DUP leader, who was in front of the inquiry for more than four hours, said officials did not draw to her attention the fact that the RHI scheme was more expensive than an alternative.
The inquiry heard that Mrs Foster had two main options available to her with regards to incentivising the use of renewable energy in Northern Ireland.
The first type was a single-up front grant to applicants, the other would provide subsidies to claimants over a 20 year period.
The grants scheme, referred to as the "challenge fund", was rejected by Mrs Foster because of administration costs.
She opted for the subsidy option, despite the fact it cost £200m more than the challenge fund.
