Rachel Reeves’s radical pension reforms risk putting retirements in danger and leaving taxpayers “on the hook” if investments go wrong, experts have warned. The Chancellor says she is “going for growth” with major reforms she will announce on Thursday in a Mansion House speech.

Changes to pensions from the Labour Party government could mean "there will be losers", it has been warned, ahead of her speech.

The chancellor is to tell City of London business leaders today about plans for pension megafunds. Meanwhile, concern over costs is growing.

Pension "mega funds" will be created under government plans to increase infrastructure investment. Reforms could "unlock £80bn" of investment, according to Treasury plans, which say bigger funds can get greater returns. Chancellor Rachel Reeves wants to imitate the way large Canadian and Australian pension schemes work.

The chancellor wants to merge the UK's pension funds, but critics worry about the impact on savers.

Chancellor of the Exchequer Rachel Reeves said the UK will introduce legislation next year to pool £1.3 trillion ($1.7 trillion) of pension savings into a series of “megafunds,” as the new Labour government tries to deliver on its pledge to boost private investment and economic growth.

Rachel Reeves will tear up workplace pension rules as part of a broader shake-up that the Chancellor claims will unlock up to £80bn in investment.

Chancellor Rachel Reeves is to set out what she is calling the "biggest pension reform in decades" in an attempt to boost growth. The government wants to merge the UK's 86 council pension schemes into a handful of "pension megafunds".
