The days when governments take shape are charged with a unique energy.
Tension, speculation and late surprises crackle through Leinster House from early morning.
Plans carefully etched over days and weeks can be cast aside at the last-minute when a disgruntled TD throws an almighty strop and forces the Taoiseach to think again.
Today a great deal will hinge on the decision around the selection of the new Minister for Justice.
Does Jim O'Callaghan return from the cold to take one of the top jobs in government?

James Browne, Dara Calleary, Mary Butler and perhaps Thomas Byrne are also in the frame for senior government roles, with Niamh Smyth viewed as a possible Chief Whip.

Plus, there is much frustration that four TDs, who are supporting the government, will get to speak from the opposition benches today.
It has all the ingredients of a fractious day that may well take the gloss off the appointment of Micheál Martin as Taoiseach.
He contents it is part of a negative agenda in some quarters, who he claims are unhappy with the composition of the new government.
