The European Union says it is up to the U.K. government to tell the 27 EU member states "as soon as possible" what action it will take after the Brexit deal was not voted on Saturday.
EU Commission spokeswoman Mina Andreeva said the EU executive took note of the vote and did not suggest a course of action.
"It will be for the UK government to inform us about the next steps as soon as possible," she said on Twitter.
Had the deal been approved, the EU parliament had planned to back the Brexit deal by Thursday evening.
