MPs will come into work on Satirday as if giving up some of their weekend is the most noble, square-jawed thing a human being is capable of doing. Many MPs will dress down, playfully tying a lavender sweater around the neck using the sleeves and wearing chinos. Some will wear trainers.
I think this will happen.
This deal is defeated in the Commons. Extension to Jan 2020, conditional on referendum. PM wants wording on referendum to be:
“Let’s get this done! YES/NO”
A sneaky way to comply but also deliver a skewed outcome. Hopefully someone has anticipated this.
