One of the things this mess has taught is the astonishing level of constitutional and legal ignorance on the part of political journalists and many actual politicians in this country. No, it is not permitted for the government of the day to simply ignore the law. Yes, there will be consequences if that happens. No, the government of the day does not have the right or even the capacity to override any such consequences.
A common talking point has been that the problem at present is largely constitutional in nature; that it reflects a broken constitutional system. While there are a few issues there, that argument is nonsense: this is not, not yet, a constitutional crisis. It is a political crisis, caused primarily by reckless, stupid and stupidly reckless behaviour from politicians and their advisors.
Quite frankly British politicians and even more so their 'Spads' seem to know very little about anything except hairbrained analogies to the United States which don't even make sense.
