Catalonia will move on Monday to declare independence from Spain following its banned referendum as the European Union nation nears a rupture that threatens the foundations of its young democracy.

Mireia Boya, a Catalan lawmaker from the pro-independence Popular Unity Candidacy (CUP) party, said on Twitter that a declaration of independence would follow a parliamentary session on Monday to evaluate the results of the Oct. 1 vote to break away.

"We know that there may be disbarments, arrests. ... But we are prepared, and in no case will it be stopped," she said.
