London: British Prime Minister Theresa May unveils her Brexit "Plan B" to parliament on Monday after MPs shredded her EU divorce deal, deepening the political gridlock 10 weeks from departure day. Britain will leave the European Union on March 29 without a deal unless MPs can force a delay or get their act together in time and come up with an alternative plan that Brussels is also happy with.

The world's fifth-biggest economy could lose preferential access to its largest export market overnight, affecting every sector, leading to rising costs and disruption at British ports. London and Brussels have spent the best part of two years working on a divorce agreement but MPs in parliament's lower House of Commons comprehensively rejected it on Tuesday.
