The RHI inquiry and the auditor who made a big impression - @SJAMcBride talks us through the latest inquiry revelations

A novel day for the RHI inquiry yesterday when a civil servant was publicly praised. That was for accepting personal responsibility for one of the multiple failures which may have contributed to the cash for ash scandal. Elaine Dolan was head of the internal audit in Arlene Foster's department during the design of the RHI scheme and the first year and a half of its operation. She told the public inquiry that an auditor working under her had not done enough to query what officials were telling him. Vinny talks to Newsletter political editor Sam McBride.
