FIne Gael's introducing legislation in the Dáil later aimed at forcing the last two TD's to hand back their Ministerial pensions.
The main opposition party says it would remove the pension entitlement from all serving members of the Oireachtas.
But the Government says Fine Gael's proposed bill is unconstitutional.
All of Fine Gael's TD's and senators who are former ministers handed back their entitlement last week, as did a number in Labour and Fianna Fail.
Only three politicians, all of them members of Fianna Fáil, have not yet indicated they will surrender their pensions.
Donegal North East Deputy Dr James McDaid said he is holding on to his on a point of principle while Galway East TD Noel Treacy said he will decide in the coming days.
This morning MEP Pat the Cope Gallagher said he has requested clarification from the Department of Finance on the issue and will later be in a better position to make a decision on his ministerial pension.
