What does that mean, if it persists, for control of Parliament? Will it compel the Tories to find a weak partner to form a government? Or a shift to control by Labour?
That would mean a huge Labour majority, comparable to that currently enjoyed by the Conservatives.
I don't think it's likely to happen that way -- though I would certainly welcome it -- but I think that unless something very unexpected happens, Labour will probably be the largest single party after the next election, and will form the next government, whether on their own or in coalition with the Lib Dems.
After Brexit, a whole section of the parliamentary Conservative Party either left politics or was driven out by Johnson, and the current party is a very disparate coalition with no real unifying ideas. They were elected to "Get Brexit Done" (i.e. put an end to the endless deadlock that had paralysed everything since the referendum) but beyond that they don't any particular idea what they want to do or why, so they're simply responding to events, good or bad, rather than trying to pursue any particular agenda, and they're making a pretty bad fist of it, largely because Johnson is such a hopeless PM.
Certainly, both Covid and the consequences of Russia's invasion of Ukraine have been huge problems not of their making, but their handling of both have been so poor, as they've taken untenable positions that they've had to abandon within weeks and reverse course, and squandered huge amounts of money on bungled initiatives during the pandemic, that we have a supposedly Conservative government presiding over the highest levels of personal taxation since WW2 and inflation at levels not seen since the 1980s.
The whole reason for voting Conservative used to be that, while no one thought they were particularly nice people, they were more competent at running the government and better at managing the economy than Labour, but now Johnson's blown that for them for a generation, I think.
