Create a new party??? Splitting the left even more is guaranteed Tory rule.
Create a new party that will appeal to voters that want more integration with the EU. That might actually attract some Conservatives that can’t get behind radical left ideals but wanted to stay in the EU. It’s only the ERG nutters that will be left behind.
Basically split both Labour Brexitiers and Tory Brexitiers into their own thing. Both of them are so hard line that they will never cooperate. What’s left will be EU enthusiasts that might, just might, pull together for closer integration / rejoin. And hopefully this new party will have a majority.
But of course if it’s more tribal red and blue that people want then bring on more Brexit! 🥹
