The Prime Minister's office has moved to clarify Tony Abbott's comments about the Government's planned changes to the Paid Parental Leave scheme, which appeared to confirm the stricter requirements would only apply to public servants.

The Coalition wants to tighten the rules so new parents can no longer claim paid leave from both their employer and the Government, something several ministers have described as "double dipping".

Labor criticised the policy and warned it would impact on low income workers who have bargained away other entitlements for better parental leave arrangements.

Tony Abbott was asked directly in Friday morning's media conference whether the Government was "considering amending your paid parental leave proposal to prevent only public servants from accessing both schemes?"

Mr Abbott replied: "Well, yes we are".

"The point I keep making about this year's budget is that it's measured, responsible and fair and what's fair about Commonwealth public servants getting two lots of paid parental leave from the taxpayer," he said.

However, the Prime Minister's office says Mr Abbott misheard the question and there is no change to the policy that was put forward in the budget.
