Britsh Prime Minister Theresa May says the Brexit vote must not be frustrated as she scrambles to win concessions from the European Union ahead of a potentially "disastrous" no-deal divorce from the bloc.

May on Sunday promised to offer lawmakers a chance to vote on her Brexit deal no later than March 12 as she warned that the "worst thing" U.K. politicians could do is to lose their focus on delivering a divorce from the European Union.

“It is still within our grasp to leave the European Union with a deal on the 29th of March and that is what we are working to do," she told reporters on her way to Egypt for an EU-Arab League summit. She's expected to meet with European Council President Donald Tusk and other EU officials in Egypt.

When the British Parliament voted 432-202 against her deal in January, one of the worst defeats in modern British history, the embattled prime minister said she would seek changes to the agreement and give lawmakers a final say, while also avoiding a no-deal that cabinet members say would be "disastrous."

A few days before she left for Egypt, several members of May's cabinet split with the government and said they would side with opposition parties to stop a no-deal Brexit.

According to Politico, the World Bank said that disorder in financial markets in various countries could negatively impact economic activity, leading to "contagion effects."
