The Johnson government needs Brexit to succeed, or rather to kid enough voters that it has succeeded. So they have absolutely no motive to sabotage it - even the current Cabinet aren't that stupid.
Some in the May government might have wanted to sabotage it, because they believed it was a bad idea but didn't have the courage to stand up to their own right wing and tell them the referendum result was obtained by deception and should be re-run on the basis of an agreed deal.
Do they want Brexit to Succeed? and if so what context? At the moment they seem intent on sabotaging their own deal over the NI protocol, and Frost seems to be demanding more even before the EU have presented their compromise proposals.
We need sensible arrangements with the EU and stability for Business is it any wonder such Intel won't consider a base in the UK when not only will companies have additional costs of not being in the single market if they want to Export to the EU, but the prospect that the agreement with the EU may go down the pan at any time and we end up on WTO rules and Tariffs.
Is it any wonder many Remainers are hacked off, I didn't have a problem accepting the result, but I did have problem with the likes of Farage campaigning on the basis of a Soft Brexit and then moving the goal posts to a Hard Brexit after the referendum, in the end we at least got some sort of deal which the government now seem intent on sabotaging as if the country didn't have enough problems as it is.
Frost complaining about this and that but hang on you negotiated this, so how stupid do you look?
