I've had that from the horses mouth too and it's the most Brexit thing I've ever heard of.
The NZ trade deal is a nonsensical failure that actually loses our country money rather than making any, destroys jobs, is terrible for the environment, makes as much sense as going to the supermarket in Inverness when you live in Bournemouth, and will probably destroy British farming but is trumpeted somehow as "a success"
If you are a housing developer looking to buy ex farm land at knock down prices it probably is, but for our country it is not.
Brexit loving Conservative Party members apparently support Liz Truss because she gives them good news about Brexit which in reality is just bad news all round, so that they can feel better about the downward trajectory Brexit has set our country on.
I honestly had no idea prior to Brexit how many people would rather be told bullshit they like than engage with a reality they don't.
