Honestly? The Reform people are probably better suited to governance than the Tory defectors, and their new comrades will treat them accordingly. Nigel Farage may gloat all he want about the likes of Robert Jenrick flocking to his banner, but the fact is no one likes defectors.
And though Farage strikes me as a man without morals and common decency, it has to be said he possesses a natural instinct for politics. He will not forget those defectors only came to him—as traitors—after the Tories had been brought to their knees, and with a mind to be rewarded with posts in a potential Reform government.
Just look at Jeremy Corbyn's "Your Party" or BSW in Germany. Defectors have a short life span in the parliamentary system …
It seems to me it all depends on Starmer's immediate future. Understandable though their desire to see Starmer fall may be, the political right in the UK could be in for a rough awakening if they continue to put all their eggs into that basket. Labour will not call an election, they don't have to do it, and why should they? And the sobering fact is that Starmer is being punished in the polls for not being red enough.
His potential replacement would to move the Labour party to the left again. They have more than three years to try and win back some of the voters lost to the Greens (and Reform, too). Reform's current roll could easily lose a lot of steam over time. I wager Farage would rather run against that pale muppet Starmer in 2029, than against a red ideologue well-liked by Labour and the left voter.
