PM says he will not speculate over policy as he grapples with how to fund tax cuts demanded by Tory MPs

Rishi Sunak has refused to commit to keeping the pensions triple lock in the next Conservative manifesto, as he grapples with how to fund tax cuts demanded by his own MPs.

The prime minister told reporters during the G20 summit in Delhi that the triple lock – which guarantees that pensions will rise by at least 2.5%, and by either inflation or earnings if they are higher – remains government policy.
