IMO this issue is partly about political survival and, as you say, there are too many contradictory solutions! I reckon there will be a lotta MPs who will be 'hounded out' of their positions after the 'dust settles' on brexit and there is no turning back! What baffles me is why some new political parties with a 'different future vision' have not been formed to oppose both the traditional 'suspects', Tory party and Labour, both having been far from impressive during this 'crisis period' that could define the future well-being of our country for generations. I can only put the reason down to an antiquated 'first past the post' electoral system that influences the choice of a significant portion of the voting population. The evolution of new challenging political parties has happened in other Euro countries before but not here even when the main ones are generally shit, disunited and unimpressive!
