Since the EU referendum, the UK has been politically paralysed, at least Westminster has.
There has been a public exploration of the power-base in the right-wing political groups in the UK. It was initially supposed to silence Conservative Eurosceptics but it has served to highlight the lack of leadership, voter-empathy and strategy in the country's ruling class.
First, the Prime Minister who'd called the EU vote, David Cameron, resigned. Then his replacement, Theresa May (what will history make of her?) called an election in 2017, less than a year after the EU vote. She lost her majority in parliament and limped on, supported by the ultra-Conservative Democratic Unionist Party, trying to push through a tough Brexit deal that no one had asked for. Eventually, her own party replaced her with Boris Johnson but he has been equally unable to push through a lightly-revised version of Theresa May's Brexit deal.
Now he has called an election. It's only next month (December) and it is likely he will get a strong majority, supported by his more (superficially) affable personality and the voters' fatigue at Brexit.
Johnson has offered to 'Get Brexit Done,' though he's been vague about what else he'll get done. Perhaps he'll last little longer than his predecessor.
