Members of parliament are expected to vote whether to block the UK from leaving the EU without a deal on 29 March, after rejecting the prime ministers withdrawal agreement.
The deal was defeated in the commons on Tuesday evening by 149 votes.
The government will publish guidance for businesses on tariffs and proposals for the Irish border in the event of no deal.
The EU said no deal plans were more important than even after the defeat.
Numerous EU leaders expressed their dismay after MPs voted by 391 to 242 votes to reject Mrs. may’s deal.
