Barcelona, Spain (CNN) The Catalan police chief appeared in a Madrid court Friday to answer allegations of sedition amid an ongoing deadlock after the banned independence referendum in Spain's restive northeast region.

Josep Lluís Trapero appeared in the Spanish capital along with two leading figures in the Catalan independence movement. Spanish authorities believe Trapero's 17,000-strong force, the Mossos d'Esquadra, didn't do enough to prevent Sunday's vote from taking place.

In Barcelona, Catalan authorities published official results from Sunday's referendum, showing 90% voted in favor of independence and nearly 8% against, with about 2% of ballots left blank. The turnout was 43% -- nearly 2.3 million people voting out of a possible 5.3 million.

A session of the Catalan parliament to disccuss the "current political situation" would be held on Tuesday, a parliament spokesman said. The Spanish Constitutional Court had banned a session of the Catalan parliament planned for Monday in an apparent attempt to prevent Catalan President Carles Puigdemont's expected declaration of independence.
