Update 3.15pm: Labour Senator Ivana Bacik has said that Garda Commissioner O’Sullivan still needs to clear up what instructions she gave to her legal team.

“It may be that [Judge] O’Higgins didn’t want to go there because he didn’t want to be seen to be giving air to allegations against Maurice McCabe that he had rejected, and he rejected so firmly by saying that he was a man of integrity, and that’s hugely important,” she said.

“But I think now [that] it’s in the public domain, certainly the Commissioner needs to make a further statement of clarification.

“I think this issue of the legislation and the Commission of Investigation Act, that clearly does preclude some comment, but here there are matters that have been disclosed.

“They’re not matters of evidence, they’re matters in relation to instruction.”
