UK prime minister under pressure to recall Parliament

British Prime Minister Boris Johnson is under increasing pressure to recall Parliament after leaked government documents warned of widespread shortages and border delays if the UK leaves the European Union without a withdrawal agreement.

Economists have long predicted such grim scenarios, but Brexit backers have dismissed the forecasts as scaremongering.

The opposition Labour Party's spokesman on Treasury issues, John McDonnell, on Monday supported the demands of more than 100 lawmakers who signed a letter demanding that Johnson cut short Parliament's summer recess to permit debate on the Brexit crisis.

Johnson is expected to underscore his commitment to leave the EU on October 31, with or without a deal, later this week when he meets with German Chancellor Angela Merkel and French President Emmanuel Macron ahead of the G-7 summit in Biarritz.
