Video: Renewable Heat Incentive scheme a 'fiasco', says Nichola Mallon
First Minister Arlene Foster is facing fresh calls to resign following new revelations over a bungled heating scheme set to cost Northern Ireland upwards of £400m.
The SDLP's Nichola Mallon described it as a "total and utter fiasco".
Alliance MLA Stephen Farry said: "Questions persist as to what role she had in the original design of the scheme. Even more crucially, once she knew there was a problem, indeed a potentially massive problem identified by the whistleblower, why she didn't persistently pursue her officials for updates.
