Newly appointed British Prime Minister Boris Johnson has reiterated his pledge to leave the European Union on Oct. 31 under any circumstance, raising the likelihood that Britain could leave without a deal, as the EU has refused to reopen negotiations. Johnson said the Withdrawal Agreement negotiated by his predecessor was unacceptable and had to be reopened, a move rejected by Brussels. As Henry Ridgwell reports from London, analysts say a general election seems increasingly likely, with parliament deadlocked and the British public deeply divided.
