Even if you don’t call it “price control” (and Downing Street would prefer that you don’t), asking supermarkets to limit the cost of basic goods is an extraordinary thing for a Conservative government to contemplate.
It may not happen. If it does, it will be voluntary, say ministers – just a nudge to retailers, so they keep the cost of living down. Definitely not the sort of thing that was last attempted 50 years ago, under a weak Tory prime minister struggling to control inflation, while grappling with strikes and sliding towards election defeat. Nothing like that at all.
