The Cabinet is meeting this morning as efforts to avoid a snap general election continue.
A no-confidence motion in the Tánaiste is due to be discussed in the Dáil at 8pm tonight which could topple the Government.
There has been no comment from Leo Varadkar or Frances Fitzgerald as they arrived for this morning's cabinet meeting, one that could be this Government's last.
Health Minister Simon Harris has voiced his support for Frances Fitzgerald.
Speaking to reporters this morning, Mr Harris said there is no need for the Tánaiste to resign.
He said the issues surrounding the Maurice McCabe controversy should be dealt with by the Disclosures Tribunal, and that an election is unnecessary
"There's certainly not a need for her to resign," he told RTÉ.
"The position of Fine Gael remains the same, the position of the Taoiseach remains the same. We have a structure in place, the Charleton Tribunal, where the Tánaiste can provide all of the information and all of the facts, but most importantly where all of those facts can be adjudicated on.
"The Oireachtas and the Government took a decision to set up a tribunal so that all those facts could be brought out into the full public light, so the issues, very important and legitimate issues Sgt Maurice McCabe has raised, can be addressed in full.
"I believe that the best place to adjudicate on these issues is the tribunal, not on the floor of Dáil Éireann. That's been my view throughout this."
Tánaiste Frances Fitzgerald’s position in Government was last night deemed to be “untenable” by the opposition and many of her own ministerial colleagues as talks to avoid a general election entered the 11th hour,write Daniel McConnell, Fiachra Ó Cionnaith, Elaine Loughlin, and Juno McEnroe.
Newly released documents show Ms Fitzgerald’s defence of the May 2015 McCabe email scandal is in tatters after it emerged that she received three emails advising her of the legal strategy by the former Garda commissioner against Garda whistleblower Sergeant Maurice McCabe.
None of these emails were sent to the Disclosures Tribunal despite their high significance.
She has repeatedly claimed she did not know anything until May 2016.
Despite the information, Taoiseach Leo Varadkar insisted he still had “full confidence” in Ms Fitzgerald as he held a late-night meeting with Fianna Fáil leader Micheal Martin in a bid to avoid an election. However, his stance has been criticised, given that he knew of the new emails and their significance since “over the weekend” and yet he continued to express confidence in her.
