why would someone in the ruling party actually defect at this stage, with 3 years until the next GE
- Its upto 3 years so an election could be called much sooner.
- If the politician actually has values and they want to work in a party that aligns with those values
- If an MP just saw Labour's vote get crushed in local elections jumping ship now might keep them their seat.
- (Edit) Being in the ruling party doesn't get you shit if you aren't one of the ones that sets the direction of that party.
why would the greens accept the defection
Greens are struggling to find good candidates, they keep having to step down not because of bad politics but because they've done some bad posts or similar. Defectors have been in the public eye for a while and so are likely scandal free.
There's also a lot of knowledge that you get about how to/how not to run a parliamentary party when you have more than 1 MP in parliament.
being demonstrated by Reform and the Tories
What issues are they facing?
Well except for the 1 that's in Jail
