The Latest on Catalonia's effort to break away from Spain and the Spanish government's response (all times local):
Catalonia's separatist leader wants the regional parliament to debate and vote on how to respond to what he called the Spanish government's "attempt to wipe out" Catalonia's autonomy.
In a televised address late Saturday, Catalan President Carles Puigdemont called plans by Prime Minister Mariano Rajoy to replace him and his Cabinet an "attempt to humiliate" Catalonia and an "attack on democracy."
Puigdemont's comments were a veiled threat to push ahead with an independence declaration for the prosperous region in northeastern Spain. They came after he joined a large protest in Barcelona on Saturday where many were aghast at the plans announced earlier in the day by Rajoy.
Puigdemont called Rajoy's move the "the worst attack" on Catalan people and institutions since Gen. Francisco Franco's abolishment of Catalonia's regional government in 1939.
The speaker of the Catalan parliament says Spain's central authorities have made an effective "coup d'etat" in what she called an "authoritarian" attempt to take control of the northeastern region.
Legislator Carme Forcadell says in Barcelona that Spanish Prime Minister "Mariano Rajoy has announced a de facto coup d'etat with the goal of ousting a democratically elected government."
Forcadell said the move is "an authoritarian blow within a member of the European Union."
Rajoy's conservative government is likely to obtain the national Senate's backing next week for extraordinary powers that will allow him to dissolve the Catalan parliament and call an early election. The measures include the sacking of Catalonia's separatist leaders.
Rajoy said the regional parliament will have its powers limited, but will remain in place until new lawmakers are elected in less than six months.

Assemblea Nacional Catalana vice president Agusti Alcoberro calls the Spanish government's move a "repressive escalation" aimed at "wiping out Catalonia as a political nation."
Catalan regional authorities are joining hundreds of thousands protesting in Barcelona in a massive show of support for independence. They are also calling for the release of two prominent activists who have been jailed while awaiting possible sedition charges.

The Spanish government wants to sack Catalonia's separatist leaders and call a new election using previously untapped constitutional powers to take control of the prosperous region.

The vice president of the Spanish Senate says a session next Friday will vote on measures proposed by Spain's government to take control of the northeastern Catalonia region.
Conservative senator Pedro Sanz told reporters the governing body of the top legislative chamber is setting up a special commission of 27 senators to make the first assessment of the measures on Tuesday.
Regional Catalan President Carles Puigdemont can make an appeal of the measures by appearing before the commission before Thursday at noon or by sending an envoy.
The special commission is then expected to approve a final proposal that will be taken to the plenary session on Friday for final approval. The ruling Popular Party has an absolute majority in the chamber and is expected to receive wide support from opposition senators for measures to keep Spain unified.
