The Minister for Employment Affairs and Social Protection has said she will bring a proposal to Cabinet next week seeking to address a pensions anomaly that affects 42,000 people.

Regina Doherty insisted that she wants this resolved in a speedy and timely manner, that the current situation is unfair and that it needs to be fixed.

This issue arises from changes made in 2012 to how state pension contributions are calculated which has resulted in thousands of people losing up to €30 a week.

Fixing the anomaly could cost up to €70 million.

There were calls from Fianna Fáil last year for the government to fix the anomaly.

Minister Doherty said she can't guarantee this will be fixed immediately but she would fight very hard for pensioners.

Speaking in the Dáil today, the deputy leader of Sinn Féin Mary Lou McDonald called on the Government to reverse what she described as the 'discriminatory' 2012 changes to the state pension.

She said "this discrimination disproportionately affects women who exited the workforce to raise children and look after families, and who then returned to employment later in life to qualify for the maximum payment".

The matter is set to be discussed by a Cabinet sub-committee today before going before a full Cabinet next week.
