New report recommends an increase in TDs in the Dáil and constituency changes
Finance Minister Paschal Donohoe is the big winner from a review of constituencies that will see the overall number of TDs increase by two.
The Dublin Central base of Mr Donohoe is to increase from three seats to four, meaning his future in Leinster House is significantly more secure.
The area is not a traditional Fine Gael stronghold and Mr Donohoe faced an uphill battle to retain his seat last year alongside Sinn Fein's Mary Lou McDonald and Independent Maureen O'Sullivan.
A report from the Boundaries Commission also recommends increasing the number of TDs in Cavan/Monaghan and Kildare South by one each.
However, it says the constituencies of Offaly and Laois should be reunited into one five seat constituency. Before the last election they were separated into two three seat constituencies.
A section of North Tipperary that was moved into Offaly for electoral purposes will revert to the status quo.
Overall, it says the number of TDs should be increased from 158 to 160.
And it says there should be 39 constituencies , of which 13 will be five seat, 17 four seat and 9 three seat.
Wicklow should become its own constituency - losing East Carlow, the report says.
But the report made limited changes in a move that has surprised TDs
In the Dublin the vast majority of constituencies remain unchanged. There will be some redrawing of the boundaries between Dublin Rathdown (3 seat) and Dún Laoghaire (4 seat), and between Dublin North-West (3 seat), Dublin Bay North (5 seat).
Along with its extra seat Cavan/Monaghan will take in some of the population currently categorised as Meath East.
The rest of the constituency of Meath East should remain as a 3 seat constituency. No changes will be made to Meath West, Louth and Longford-Westmeath.
The constituency of Donegal will remain a five-seater but some of south Donegal will continue to vote in Sligo-Leitrim.
Small changes have been made to the boundaries in Roscommon-Galway constituency, Galway East and Galway West but the number of seats in each constituency remain static.
Mayo with some additional population from Galway West should remain a four seat constituency.
In the south west, Clare is unchanged. Some population from Tipperary is to be moved to the Limerick City constituency.
There should be no change to the five Cork constituencies or to Kerry, Waterford and Wexford.
