The trouble is Trisher, if you put that in the DM some people would be up for it.
I do agree that there is no hurry and the LP can take it's time to decide how it goes forward. That will have more effect on who they chose as a leader than looking backwards.
I do understand Grandad's views about the unions but they seem to need a face-lift if they are to appeal to the new generations. Many who would not have seen themselves as "workers" in the past but as aspiring middle-class, now do as the class system does not have the simplicity or cohesion it once did. You also have a younger tranche who were educated to a higher level so would, perhaps, not have seen themselves as trades unionists. However, they are not wealth-gatherers either so probably do need an updated union structure. And there are the so-called "self-employed". Big changes for everyone to cope with.
The English Nationalists of the Tory party may have held these changes at bay with Brrrrexit but they too will have to face them sooner or later. Their new voters were won mainly from the 'leave' contingent and, as the YouGov analysis tells us age is still the biggest dividing line in British politics. In fact, they say, for every 10 years older a voter is, their chance of voting Tory increases by around nine points, and the chance of them voting Labour decreases by eight points.
Without Brexit, they will not have the same pull in the next election whether they run the full five years or not. The Labour Party has to look ahead and see how it can increase its appeal when we know what Brexit we have got and what it is doing to our country.
