Catalan speaker posts bail in Spain

Spain's Supreme Court says a judge has ordered the release of the Catalan parliament's speaker after bail was posted.

Carme Forcadell spent the night in jail as part of a rebellion investigation following the parliament's declaration of the region's independence.

The court said Friday that bail of 150,000 euro ($A234,000) had been registered and a judge had signed a ruling for Forcadell's release.

The judge jailed Forcadell and four other parliament members on Thursday but set bail after they agreed to either renounce future political activity or do it within the constitutional framework. The judge also set bail for the other four.

The five, and one other who was released, had been quizzed in the rebellion investigation following the Catalan parliament's October 27 secession declaration.

Eight members of the now-defunct Catalan government are in jail in the case while former regional president Carles Puigdemont and four other ex-cabinet members fled to Belgium where they are fighting extradition.
