The grand coalition governments of the EU are not in any way better. They just result in bickering and gridlock because parties that hate each other get stuck in the same room.

This is your pet issue, completely based on the grass looking greener on the other side.

The gridlock is real whether it happens inside or outside the party. This is partly why we're here in the first place! Starmer is out because he couldn't do coalition management inside the Labour party.
