The true lesson to be drawn from the British general election is not, in other words, that Labour voters were persuaded of the advantages to them of electing a Tory government. It was, rather, that they were fed up with the three and half years of a parliament that had failed (or refused) to give effect to the decision they had reached in the 2016 referendum. The lesson is not so much about how to win an election as about how to lose one.
What Boris Johnson managed, but Labour failed to do, was to keep faith with the British people. He understood the Brexit decision was not, as so many who opposed it insisted, a terrible mistake by those who didn't understand what they were doing, but was, rather, a considered judgment as to the impact EU membership had had on their lives.
The real puzzle is why Jeremy Corbyn, the Labour leader, failed to grasp this. It was, after all, his Labour voters in the North and Midlands, whose jobs, wages, housing, education and health services had suffered most and who had blamed EU membership for what they felt was a loss of control over their own affairs.
When Labour MPs joined the majority in parliament apparently determined to frustrate the Brexit that lifelong Labour voters had voted for, those voters then voted for the one politician who would, they believed, do what they wanted.
The election result was therefore hardly a surprise. It was a totally foreseeable rebuff by voters to all those politicians who thought they "knew best", and who presumed to substitute their opinions for those of the voters who had elected them.
Those politicians took a dangerous gamble with the voters' faith in representative democracy when they ignored the wishes and opinions of those who had sent them to parliament.
Boris Johnson's victory did not, in other words, materialise out of thin air. It was a justified reward for nothing more complicated than simply trusting (and representing) the people - something that should come naturally to all democrats.
If lessons are to be drawn here in New Zealand, they are to be learned by Labour rather than by right-wing politicians. It is, after all, the left that claims to represent - as Jeremy Corbyn himself put it - the "many, not the few". That claim can at times seem somewhat hollow, as Corbyn demonstrated.
The British election could have turned out very differently if Corbyn had taken one simple step. If he had committed, at the beginning of the campaign, to delivering Brexit, the whole issue would have been negated as a point of difference between the two major parties, and Labour voters would have been able to decide their vote on a range of other, and more familiar and traditional issues, which would in most cases have meant that they stayed loyal to Labour. Parting company with the voters, especially your own, is never a good idea.
