LONDON—The British parliament is set for a September showdown between Prime Minister Boris Johnson’s “do or die” pro-Brexit government and those implacably opposed to leaving the European Union without a divorce deal.
Johnson says Britain will leave the EU with or without a deal on Oct. 31 and is refusing to negotiate with Brussels until it agrees to change the Withdrawal Agreement, the deal it negotiated with his predecessor Theresa May. Brussels says it won’t renegotiate.
