They don’t and too hell with the common Brits. God I miss the Iron Lady.
Thatcher was part of the problem, frankly.
Years after leaving office, she declared the EU unreformable, corrupt, socialist etc. but she never advocated withdrawl. Everything she later said about the EU was obvious in the mid 1980’s but she never did anything about it.
While in office she appeased pro europe scumbags in the Conservative Party while detroying her political capital on second tier issues like the Community charge.
