So it looks like the British people really do want to see a clear outcome on Brexit.

The exit poll, published by British broadcasters the minute the polls closed, is predicting a massive win for the Conservatives and a massive loss for Labour.

Immediately, the pound soared on foreign exchanges – a sign of relief that a clear decision appears to have been taken: Brexit goes ahead.

But a result of this magnitude will also set in train a series of conflicts in UK politics and not all about Brexit

To win a majority in the House of Commons you need 326 seats. On the basis of this exit poll, Boris Johnson is projected to win to 368, 50 more than Theresa May won in 2017.

That would give him a majority of 86 in the House of Commons – the biggest since Margaret Thatcher in 1987.

If that pans out overnight, or even something close to it, it will enable Boris Johnson to "get Brexit done".

Having purged the Conservative Party of its leading dissidents on Brexit, he can barrel the Withdrawal Agreement Bill through the parliament in the weeks ahead, in time for the 31 January deadline.

That's the easy bit. Then comes the conflict with the EU over the nature of the future relationship between the EU and the UK. And that tussle will almost certainly lead to internal conflict within the Conservative Party over what kind of Brexit the different party factions want.

Labour's slump to 191 seats, if projections are correct, would be worse than Michael Foot in 1983.

Losing 71 seats would represent an earthquake for the party. This is not simply another lost election, it is a verdict on Jeremy Corbyn's leadership, and the direction the party has been going in under him.

The party infighting has broken out already on social media, with MPs quick to start apportioning blame. Expect open warfare in the days ahead.

Shadow Chancellor John McDonnell said the result was "extremely disappointing". He thought it would be much tighter than the poll is predicting.

Mr McDonnell rejected the suggestion that it represents a repudiation of Mr Corbyn's policies. He said it was a Brexit election, and that Brexit dominated all debate.

He accepted that people want to get Brexit out of the way and believed they would refocus on other policy issues later. But that may be too late for his wing of the party. A massive fight for the soul of that party looms.

And after nine years of Conservative government, with all the austerity policies the Cameron government pursued, for Labour to get a kicking of the magnitude suggested by this poll, a fundamental reassessment of the party's offering to the voters will come.

But clearly its Brexit stance, convoluted and confusing, has utterly failed to convince voters who wanted clarity.

The SNP is forecast to win 55 seats out of 59. That is close to a North Korean level of dominance.

I don't expect that number will hold up, a jump of 20 seats from the existing 35 seems too much.

But even a gain of half that many would set up another conflict in UK politics in the years ahead: the push for Scottish Independence.
