"Spain's Supreme Court has sentenced nine Catalan separatist leaders to between nine and 13 years in prison for sedition over their role in an independence referendum in 2017."
“Three other defendants were found guilty of disobedience and fined, but will not serve prison sentences.
The 12 politicians and activists had all denied the charges.”
