'Cash-for-ash' inquiry: Arlene Foster says she regrets spiralling costs

DUP leader says she believes Sinn Fi(C)in protests over RHI costs were an excuse to bring down power-sharing executive

Northern Ireland's former first minister Arlene Foster has told the inquiry into the green energy scheme that resulted in the collapse of the power-sharing government that she deeply regretted its spiralling costs.

The renewable heat incentive (RHI) programme was championed by Foster when she was the devolved enterprise minister but its costs ran into hundreds of millions of pounds.
