There are calls for the Taoiseach Leo Varadkar to clarify what agreement, if any, has been made in relation to a review of a Brexit backstop.
It comes as Mr Varadkar yesterday rejected claims that he has made a major concession to the UK in the Brexit talks.
He said the backstop on maintaining an open border could be reviewed at a later date.
Fianna Fail's Brexit Spokesperson Lisa Chambers called on the Taoiseach to bring clarity to the Government's position on a potential review of a Brexit backstop.
Mr Varadkar travels to Finland today, where Brexit is set to top the agenda in a series of meetings with Finnish leaders.
The Taoiseach and European Affairs Minister Helen McEntee will meet with the Finnish President Sauli Niinistö and Prime Minister Juha Sipilä.
The talks will primarily focus on Brexit as well as the European summit in December and migration issues.
