Available for over a year

DUP leader Arlene Foster's time in front of the RHI Inquiry came to an end yesterday after she gave seven hours of evidence. So how did she do? Amongst other things Mrs Foster said Jonathan Bell had pressed a "nuclear button" by going public with claims that DUP advisers delayed plans to shut the flawed energy scheme as its budget spiralled out of control. Mrs Foster told the inquiry that "paranoia set in with Jonathan" when he felt the party was trying to blame him for the debacle. That prompted him take a "route with Stephen Nolan which caused the downfall of the executive". Stephen spoke to Newsletter political editor Sam McBride.
