LONDON/BRUSSELS—Prime Minister Theresa May’s Brexit strategy came under attack from all sides Nov. 12, increasing the risk that her plan for leaving the EU will be voted down by Parliament and thrust the United Kingdom toward a potentially chaotic “no-deal” Brexit.
In a sign that Brexit talks could go down to the wire, EU sources said they want clarity from London by the end of Nov. 14 at the latest if there is to be a summit this month to approve a Brexit deal.
