Former pensions minister Steve Webb is believed to be joining Royal London, whose boss has been an outspoken critic of some of the coalition’s reforms.

Mr Webb, who lost his Liberal Democrat seat in May, was credited with introducing the biggest shake up in the industry for a generation.

Further change cannot be ruled out, particularly after the appointment of pensions campaigner Ros Altmann as Mr Webb’s successor.

Phil Loney (left), Royal London’s chief executive, last year described Mr Webb’s plans to cap charges for workers automatically signed up to pension schemes at 0.75 per cent as a “headline grabbing” policy.

In an interview with Daily Business in May, MrLoney said the new minister’s biggest test could be convincing her new bosses in government that some of their current thinking “is a little wrong-headed”, including an election commitment to curtail tax relief for higher rate taxpayers.

“We are hoping this will not happen as it is not a smart thing to do,” he said. “People imagine tax relief on pensions is a subsidy, but if you do not give people the relief then they are being taxed twice, and this disincentivises them to save just when they are at their peak earnings powers.”

He’s also got an issue with the £1 million cap on pension pots. “It sounds like a lot, but buys a pension of only £27,000 a year. That’s hardly a life of luxury,” he said.
