Listen: First Minister Arlene Foster responds to Jonathan Bell RHI scandal allegations
Northern Ireland's First Minister Arlene Foster has apologised for not building in cost controls to the Renewable Heating Incentive (RHI) scheme.
She was speaking to the BBC's Stephen Nolan following claims made by the former Enterprise Minister Jonathan Bell that the scheme was kept deliberately open after it was found to be flawed.
The DUP leader has denied wrongdoing over the matter.
