Government took a battering on UC, no surprise there.
Labour and the Lib Dems came under an onslaught from the audience for being alleged Brexit saboteurs.
Really just more proof that the electorate don't understand the issue.
It's like the financial crash all over again - where people assumed (or were persuaded) that a country's finances are just like their own. Now we have people treating the negotiation process like buying a second hand car, where if you walk away you haven't actually lost anything.
But there is no status quo to fall back to for the UK. Even the WTO will necessitate extracting our tariff quotas from the EU's, something which is already being disputed.
And of course most Brexiter's are so blinded by their distaste for the EU that when they see the negotiations going badly they assume it is the EU's fault, whereas of course it is the UK's fault for initiating the Article 50 countdown before it was in any way prepared, wasting time on an election, agreeing to the phasing of the talks and giving up all leverage it had in negotiations apart from the ability to pay a huge amount of money to the EU, something which is completely unpalatable to the Leave vote.
As such we are actually careening towards the utter madness of no-deal. We're not at 50/50 odds on that yet, but they are definitely shifting in that direction.
