Hundreds of thousands of older married women are potentially missing out on bigger state pension - but won't be contacted by the Department for Work and Pensions (DWP).
The DWP has already identified more than 230,000 women who are thought to have been underpaid their state pension following an IT blunder.
But a document supplied by the DWP to an appeal Tribunal last year reveals there are "low hundreds of thousands" of older married women the Government has "no plans" to contact.
