Fianna Fáil leader Micheál Martin has confirmed his party will table a motion of no confidence in the Taoiseach when the Dáil resumes later this month.
Micheál Martin's also hit out at the Labour party in the fallout from the Fennelly Commission report, saying it's 'extraordinary' that the junior coalition party is continuing to support Enda Kenny's position on his handling of the matter.
The report found that Enda Kenny didn't force Martin Callinan to quit his position, although the Garda Commissioner's decision to do so was a direct result of a top civil servant being sent to his home.
Deputy Martin said: "We will be tabling a motion of no confidence. Yesterday I said I felt the way the Taoiseach presented all this was neither credible nor tenable.
"Having read the report in full, his behaviour in all this is neither credible, nor tenable nor acceptable and it demands a motion of no confidence.
"Certainly the Government backbenchers may circle the wagons (in the event of a vote), but that's a reflection on them."
Enda Kenny said this morning that rather than replying to comments made by Micheál Martin, he preferred to accept the findings of a "former eminent Supreme Court judge (Justice Nial Fennelly), and the conclusions speak for themselves."
