Farage announced that Reform UK is abandoning its previous manifesto plans for substantial tax cuts, stating they are not realistic given the current state of national debt and finances.
He also refused to commit to the triple lock on pensions, arguing it is impossible to make such projections between now and a future general election.
The Reform leader predicted a general election by 2027, which he believes will be triggered by an "economic collapse" forcing the Chancellor into policies unacceptable to the Labour left.
Conservative shadow chancellor Sir Mel Stride criticised Reform UK's economic credibility, citing their shifting promises and alleged failure to find savings in local government.
