The Tories are to make a last ditch bid to amend the finance bill and save the bereavement allowance for widows over 60.
Tory Treasury spokesman Nick Gibb will put down an amendment to the bill this week.
Before the Budget, widows were entitled to an allowance equal to the married couples allowance for two years following their deaths, but this has been replaced by a means-tested payment that will be available only to widows under pension age.
Gibb says: “People in their early 60s are seen by Labour as a soft touch. They are being taxed and taxed again and again. It is quite disgraceful.”
