Boris Johnson is threatening to derail Rishi Sunak’s efforts to thrash out a new Brexit deal after warning that ditching the Northern Ireland Protocol Bill would be a “great mistake”.
The former Tory prime minister was accused of being a “nuisance” and “wrecker” as he was criticised for encouraging the DUP to resist a compromise over the post-Brexit arrangements. A source close to the former PM said: “His general thinking is that it would be a great mistake to drop the Northern Ireland Protocol Bill.”
