article: David McIlveen, who is still a member of the party, said Mrs Foster had "seriously misjudged" public anger. Mrs Foster set up the RHI scheme in 2012, but its lack of cost controls has left NI taxpayers with a Â£490m bill. A DUP spokesperson said she continued to receive "overwhelming support" within the party and beyond. "Former MLA David McIlveen is entitled to his personal opinions, however, this is the first time that he has articulated any view since losing his seat," they said. On Wednesday, the party said the assembly may be recalled next week to approve emergency legislation to deal with the overspend. Mr McIlveen, who is the son of Free Presbyterian minister and close friend of the late Rev Ian Paisley, Rev David McIlveen, questioned Mrs Foster's handling of RHI in an article for the News Letter. He suggested Mrs Foster was personally responsible for turning the scheme into an "omnishambles" and said she will come under increased pressure from her own party. He drew comparisons with the treatment of former DUP leaders Peter Robinson and the Rev Ian Paisley. Mr McIlveen wrote that Mrs Foster was now "deeply damaged" and unlikely to lead the party into the next election after becoming an "electoral liability". "Does a party obsessed with elections want to move forward with a leader who appears incapable of facing up to their mistakes?" he asked.

"I think that I am maybe in a better position than David McIlveen to make an assessment of the view within the party." However, Ulster Unionist leader Mike Nesbitt said Mr McIlveen's intervention was "significant". "I know you were reporting it as David McIlveen breaking ranks and that is true, but equally true is that he is joining the ranks of those pointing the finger of blame," he said. "And we're not talking about bit players here, David McIlveen was an assembly private secretary for Arlene Foster, he's joining Jonathan Bell who was a junior minister and also a minister for the department of enterprise." Mr McIlveen also criticised Mrs Foster's treatment of Jonathan Bell, who in December, made a series of allegations about the DUP's involvement in the scheme. "When one of her own party members broke rank to express their concern about the scheme, rather than approach the issues raised with a listening ear, the default position was to attack the personal integrity of the individual raising the concerns," he wrote. "In any other context, Jonathan Bell MLA would be called a
