The new Agriculture Minister will be named around 12.30 this afternoon.
The Minister will be nominated after Leaders' Questions.
Dara Calleary is widely tipped to be promoted - however, Charlie McConalogue, Anne Rabbitte and Thomas Byrne have also been mentioned in Fianna Fáil circles.
There's also speculation that Longford Westmeath Fianna Fail TD and newly appointed Junior Minister Robert Troy could be in the running to get the Chief Whip position if Dara Calleary was to be moved.
