A Fine Gael backbencher has said he should have credited Labour's Joan Burton with passages of a speech he made in the Dáil.

Three passages of Terence Flanagan's speech in the debate on the Finance Bill were identical to the contribution made by the Labour Deputy leader the previous evening.

The Dublin North-East TD initially said it was all his own work and that he had nothing to apologise for, when confronted by a journalist.

'I didn't nick her speech', he said.

But this morning after contacts with party headquarters, Mr Flanagan issued a statement conceding that he drew on some elements of Ms Burton's contribution in his 1,500-word speech.

He said he should have acknowledged that and regretted not doing so.
