LONDON - Prime Minister Boris Johnson told French President Emmanuel Macron on Tuesday British officials would continue to work hard to secure a Brexit deal before a summit later this week in what his spokesman described as a constructive discussion.

Asked about comments attributed to the European Union's chief negotiator Michel Barnier that a legal text for the deal should be agreed by the end of Tuesday, the spokesman said Johnson was aware of the time constraints.

He added that if a deal were secured, Johnson would expect parliament to work round the clock to pass the necessary legislation for Britain's departure before the prime minister's Oct. 31 deadline.
