Re: So, to sum up. . .
And Parliament does not negotiate with foreign governments.
No man is an island, and no country exists in a vacuum.
Of course governments negotiate with each other. It's called diplomacy. Even North Korea interacts with its neighbours.
To state that "Parliament does not negotiate with foreign governments" is wilfully misrepresenting normal relations with other countries as adversarial. It's this sort of bollocks that has got us into the trouble we are in in the first place.
