Catalonia's President Carles Puigdemont has ruled out dissolving the regional parliament and calling a snap election. The Spanish Senate is set to approve suspending Catalonia's autonomy on Friday.
Catalan President Carles Puigdemont said on Thursday that he will not initiate a snap election, despite earlier reports that he would do so to defuse the ongoing standoff between Barcelona and Madrid over the region's drive for independence.
The upper chamber Spanish Senate, which mostly supports Rajoy's hardline stance against Barcelona, is set to approve that decision on Friday.
The government has never before evoked Article 155 against any of the country's 17 autonomous regions.
Puigdemont has accused Rajoy of wanting to carry out "the worst attack on institutions and the Catalan people" since Francisco Franco, the dictator who ruled Spain from 1939 to 1975. Franco's government suppressed Catalan culture and forbade the official use of the region's language.
Madrid and Barcelona have been locked in a standoff since Catalonia held a disputed independence referendum on October 1 in which 90 percent of voters opted for secession.
Spain had declared the vote illegal and voter turnout was only 43 percent on polling day. Puigdemont nevertheless said after the vote that "the citizens of Catalonia have won the right to an independent state in the form of a republic."
