The United Kingdom's House of Commons is scheduled to vote Tuesday on whether to proceed with Prime Minister Theresa May's plan for Brexit, the U.K.'s exit from the European Union.
But whether the vote will proceed as planned remains uncertain, as opposition inside and out May's Conservative Party makes its prospects look dim. Protest resignations from May's own government are expected Sunday and Monday, but May's office says the vote will go forward.
May has warned fellow Tories who oppose her plan that its failure may lead to a general election, a new government, and the "very real risk of no Brexit" at all.
The deal under consideration was settled with EU leaders late last month, and European Commission President Jean-Claude Juncker warned critics it is the best realistic option.
