The Minister for Arts has refused to answer any further questions about John McNulty.

Heather Humphreys attended an event at The National Gallery in Dublin this morning where she ignored waiting reporters as she entered and exited the event.

Yesterday the Taoiseach admitted he was responsible for the controversy surrounding Mr McNulty's candidacy for the Seanad bye-election, and his appointment to the Board of IMMA.

Kenny said yesterday of the scandal: “I wouldn’t say it was my finest hour, and I take responsibility for this having evolved to what people might imagine it is.”

Speaking in Roscommon last night, the Taosieach said: I accept responsibility perhaps for not taking a closer view of how this evolved and what I can say to you is that it’s not going to happen again, believe me.”

“One thing that we are going to do in discussions with our Labour colleagues in Government is to put in place an absolutely transparent process where people appointed to boards can only be appointed on the basis of having applied through the public system.”

When asked about Enda Kenny's comments yesterday, Heather Humphreys walked passed reporters giving only a stony silence.
