Prime Minister David Cameron has said the state pension will continue to rise by at least 2.5% a year until 2020 if the Conservatives win the next election.
The "triple lock" system, which ensures the state pension goes up by whichever is higher - inflation, wages or 2.5% - will remain in place, he said, the BBC reports.
At a time when benefits for younger people are being cut, Cameron (pictured) said it was "fair" to prioritise pensions.
Labour said it supported the triple lock "in principle".
The announcement was the "first plank" of the Conservative general election manifesto, the Prime Minister said, but he dismissed suggestions it was a purely political move aimed at getting older voters to rekindle their support for theTory party.
Research last year by YouGov suggested the UK Independence party (UKIP) draws the majority of its support from older people - far more so than the Conservatives, Labour or the Liberal Democrats.
Cameron said the move was a choice "based on my values" and "the right choice for the country".
"I want people when they reach retirement to know that they can have dignity and security in their old age," he told the BBC.
