I’m surprised.
The old, traditional left used to be very anti-EU until Blair came along and embraced it. Galloway is a holdout of the ‘old left’. I actually prefer the old left to the virtue signalling, degenerate neo-left that espouses hypocrisy, idpol and globalism. At least the old left represented by people like Galloway, Tony Benn, and Dennis Skinner recognise the importance of nation-states with governments that are accountable to the people they govern rather than corporations and globalist elites for whom the EU is a vehicle to their ambitions.
