Government's Parliament Majority
I found the article a little vague. Are they talking about not Brexiting or just going back to the drawing board on the details?
Afaik, what they're actually talking about now is not accepting the proposal. What comes after that, if they don't accept it, is anybody's guess. Likely various opponents of the plan have various ideas about what they want to happen after non-acceptance, but it's all uncharted territory.
