"There is no getting away from it. That was an absolutely devastating blow," Steve Baker -- a member of the European Research Group of Conservative lawmakers which opposed May's plan -- told BBC radio on Wednesday.
May should now push for a free trade agreement with the European Union but Britain should also be prepared to leave the EU without a deal, Baker said.
He echoed comments from other members of the pro-Brexit ERG group who have said they will support May's government in a confidence vote scheduled for later on Wednesday. (Writing by William Schomberg, editing by James Davey)
