Of course labour could abrogate CPTPP, parliament is sovereign, but it would pay a political price to do so and would need to make its compromises with the EU openly. Good, the Social Chapter was a disaster in my opinion (both for me and for you), and I don't want a repeat of that.
Does this mean that Brexit will indeed be a principal driver for how you vote? Ie. any attempt at, say, joining a customs union, will bring any party too close to the EU for your tastes and thus prompt a vote for the Tories.
