Farage, who is the MP for Clacton in Essex, claimed the proposals were expensive, did not have public support and would disadvantage rural and coastal areas.
“This is a Labour government that doesn’t understand that people have an emotional connection to the historic counties of this country and there’s nothing in these proposals that I can see that will be good,” he said.
“It won’t even save money. It’s a dog’s dinner, a bad idea.”
Suffolk, Norfolk and Essex county councils, which are all run by Reform, and Conservative-run Hampshire County Council, have decided to pursue a judicial review opposing the plans.
The plans are not unpopular with everyone. Many district councils are still supportive of the government’s proposals and have attacked the decision to take legal action.
