LONDON—The British government is working on the assumption that the European Union will not renegotiate its Brexit deal and is ramping up preparations to leave the bloc on Oct. 31 without an agreement, senior ministers said on July 28.
Boris Johnson, who took over as British prime minister on July 24 with a promise to deliver Brexit by the end of October “no ifs or buts”, plans to seek a new exit deal with the EU. The EU has said repeatedly that the deal cannot be reopened.
