The Taoiseach has said he doesn't believe any law was broken by Leo Varadkar when he shared a confidential agreement with doctors.
Micheál Martin has said the Tánaiste's actions were not best practice but that no major advantage was given to anyone by sharing the agreement.
The pressure on Leo Varadkar has been building over the weekend ahead of his statement to the Dáil tomorrow.
This morning the Minister for Business was conspicuous by his absence from the announcement at Government Buildings of 300 new jobs by pharma company Pfizer.
Instead it was Taoiseach Micheál Martin who made the announcement, and took questions on Leo Varadkar's sharing of a confidential IMO agreement with a rival GP union.
The Taoiseach said he has confidence in Leo Varadkar, but deflected most questions saying the Tánaiste will have his own chance to answer them in the Dáil tomorrow.
For the opposition, including Sinn Féin's Louise O'Reilly, there's plenty of questions.
The Tánaiste's defence largely centres around the argument that most of the information in the IMO document was already in the public domain before he shared it with a friend of his who was heading a rival union.
