David Cameron and Nick Clegg will reaffirm their commitment to reforming the state pension in a mid-term review of the coalition's progress.
The review, which will be published later today, will assess how well the coalition has met its aims so far and set out which areas the government will focus on until 2015.
In particular the review will reaffirm the government's promise to reform state pensions so that the system rewards individual saving and cap the cost individuals pay for long-term care.
In a joint statement, the leaders said: "Today, at the half-way point in the parliament, we are taking stock of the progress we have made in implementing the coalition agreement that we signed in May 2010.
"But we are also initiating a new set of reforms, building on those already underway, to secure our country's future and help people realise their ambitions."
The affirmation comes after a six-month delay to the white paper which pensions minister Steve Webb has promised will set out the design of the universal flat rate state pension.
Last year, it was rumoured that Cameron had personally intervened in state pension reform over fears it would alienate elderly Conservative voters.
