'We need a full independent inquiry' – Alliance’s David Ford reacts to DUP and SF RHI claims #NolanRHI

The DUP have come out on the attack over RHI - accusing the BBC of bias and having a go at Sinn Fein. Their MP Sammy Wilson has alleged the "BBC aided and abetted the political enemies of the DUP to create a crisis". The party have also published an election leaflet in which they claim a number of facts, including that there will be "no future overspend". That statement is at odds with what DUP MLA and Economy Minister Simon Hamilton said just two weeks ago. Stephen talks to Alliance Party MLA David Ford.
