Pressure is growing on Gordon Brown after 144 MPs signed a motion demanding a statement.
The calls came as the Public Administration Select Committee condemned the government’s inaction over the issue, saying “justice delayed is justice denied”.
The Conservatives say Gordon Brown’s pledge that a statement would be made before Christmas is one of a number of broken ministerial promises on the subject.
Shadow financial secretary to the Treasury Mark Hoban says: “A motion backed by 144 MPs states that Parliament should not break up for Christmas until we have had the statement on Equitable Life that Gordon Brown promised. We owe it to policyholders to hold him to his word.
“Gordon Brown has sought to block, frustrate and delay the Ombudsman’s report. It is time for the Government to apologise for the way regulators have failed policyholders and establish a scheme to make payments to those who have lost out.”
