Parliament voted last night to prevent the final Brexit bill from being passed using a lower standard of scrutiny, basically forcing the government to make the final EU withdrawal bill a full Act of Parliament.
Last night, the BBC interviewed the Justice Minister and he was literally like a broken record. Every answer he gave was essentially identical, except for the use of different words and putting them in a slightly different order. After 5 answers like that, I was getting pretty irritated but also quite impressed by this guy's vocabulary - and his steadfast adherence to his own mantra that this defeat for Theresa May was 'no big deal' (though he didn't actually describe it like that!) Contrary to what the Justice Minister repeatedly said, I believe it is a big deal - not least because it shows just how precarious May's negotiating position is.
Part of the problem is that May is being forced into a 'Hard Brexit' by a combination of her own party and the attitude of the EU - anything less than Hard Brexit is seen as a betrayal of the vote by Brexiteers, but 'Soft Brexit' (aka 'having your cake and eating it) has all but been ruled out by the EU. Ironically, that means that the right wingers like UKIP and the Tory right are actually more in step with the EU insomuch as they both realise that Soft Brexit will not/cannot happen for a multitude of reasons.
But - Soft Brexit is much more popular with the British people than Hard Brexit... given that 48% of UK people voted to Remain but must accept that the UK is leaving the EU, almost all Remainers would prefer a 'Soft Brexit'. That means that it only takes a small proportion of Leave voters to favour 'Soft Brexit' for that to be the most popular option... and I'd guess that at least one quarter of Leave voters would prefer a soft(er) Brexit than what is being suggested by the likes of Nigel Farage.
What that adds up to is a very difficult position for the UK government - the people want Soft Brexit but the EU won't allow it. This is possibly the main reason why Theresa May (and the Brexiteers) would prefer for the final Brexit deal to be passed with relatively little intrusion from the rest of parliament, because they know that their 'Hard Brexit' deal is not likely to be supported by the majority of people, hence any deal they can come up with is likely to get voted down.
