The Tánaiste has confirmed that politicians and ministers will face cuts in their pay and pensions in Tuesday's Budget.

Stressing that she was confident the Budget will be passed, Mary Coughlan said the reductions in State pensions will be applied to ministers and TDs.

Speaking on RTÉ's The Week In Politics, she said while politicians had already taken reductions in salaries and expenses, the next round will also apply to pensions of existing TDs and ministers.

It is understood the cuts will be significant and the cuts in pensions will be graduated with those on bigger pensions facing proportionately bigger cuts.

Meanwhile, speaking on the same programme, Fine Gael's Fergus O'Dowd said they have been upfront to the people with their four-year plan and outlined what his party will do and how it will be done.

He said the emphasis will be on job creation and investment to grow the economy.

Labour Finance Spokeswoman Joan Burton acknowledged that despite their opposition to some of the budgetary measures, it will be legally very difficult to 'unpick' the budget if the Finance Bill and Social Welfare are enacted in law.
