The government has so far resisted offering amendments to the Pensions Bill which would ease the lot of half a million women who will have to wait up to an extra two years for their state pension under current plans.
The Bill, which is being considered by a Parliamentary committee today, proposes raising the pension age for women from 60 to 65 by 2018 as a prelude to both female and male pension ages rising to 66 in 2020.
Critics say up to 500,000 women face working up to two years longer for their pensions as a result of the proposals.
Succour for women hit hardest by the change was widely anticipated during the committee stage of the bill.
Although the government last month said it would press ahead with plans to raise the state pension age for women, ministers promised to look at "transitional" arrangements.
However, no amendment proposing such an arrangement has been tabled by coalition ministers, and pensions minister Steve Webb (pictured) has not replied to repeated invitations from the Opposition to work together on the issue.
Labour has proposed an amendment which would freeze the age at which people can claim pensions credit for a certain period of time.
It said this would provide those facing a longer wait for their pension with a small interim income.
Labour's amendment will be debated on Thursday. Under committee rules, amendments must be tabled three days in advance.
Shadow pensions minister Rachel Reeves said: "The only amendment we are debating on this issue has come from [the Labour] side of the house. I thought it would be one among a number of amendments.
"My reading was that the government would come back with amendments to be scrutinised by the committee. I wrote to the minister about the issue on 22 June and am disappointed to have had no reply."
Amendments can still be tabled at the next stage of the bill, the report stage, which has yet to be scheduled, but cannot be tabled at the third and final reading.
