Liz Truss is expected to attempt to hold a mini-budget and travel to the leaders’ summit of the UN general assembly in New York next week in the days after the Queen’s funeral. Paul Johnson, the director of the Institute for Fiscal Studies thinktank, has said the government will have to come up with a better version of the energy price guarantee next year because the one announced by Truss last week is “incredibly expensive” and “totally untargeted”. In an interview with Times Radio he said: It’s extraordinary that they didn’t publish a cost with the announcement. This could actually turn out to be the biggest single fiscal announcement in my lifetime, because this could cost £150bn. Now, how much it costs in the end is, of course, enormously uncertain, because it depends on what happens to gas prices going forward. And it depends on how long this policy is in place. One of the things that I really hope is that they’ve got teams of people working next year on thinking of something better for next winter because whilst this might be necessary this year, it’s incredibly expensive. It’s totally untargeted. It gives large amounts of money to people who don’t need it, and it means that we’re not facing the price signal that there is less gas out there. And yet we’re being massively subsidised to use gas. So if it’s possible to come up with something better, which is better targeted, then we really ought to be doing it.
