Taoiseach Enda Kenny has backtracked on his admission that he appointed John McNulty to the board of the Irish Museum of Modern Art.

Speaking after the leaders' debate last night, Mr Kenny said it was a ministerial appointment made by Minister for Arts Heather Humphreys, but that he accepted responsibility as line manager.

He said: "I dealt with this in the Dáil. I accepted responsibility for the appointment by the line minister.

"I said it wasn't my finest hour and I've changed the procedures entirely after that. Everybody now is appointed under the public appointments system - independently vetted."

However, during the debate Mr Kenny confirmed he had a role in the appointment of the Fine Gael by-election candidate to the board of IMMA.

During the debate, he said: "What I did was make an appointment that did not need to be made."
