The Arts Minister 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 blanked waiting reporters.

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.

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