An ex-UK prime minister, Gordon Brown said the UK is in danger. He warned of economic disaster when the UK leaves the European Union, especially if the UK leaves without a deal. He said this is because many people in the UK want independence for their country. He said the UK is no longer a united kingdom.
The UK is four countries - the three nations of Great Britain (England, Scotland and Wales) and Northern Ireland. Most people in Scotland want to stay in the EU. There are now talks of Scottish independence. People are also talking about a possible reunited Ireland. Brown said: "Nationalism is now driving British politics."
