He went on to back the Spanish government, insisting the independence referendum was illegal and undemocratic, warning that the region needs to ensure constitutional order and the rule of law.
Puigdemont also criticised Spain's King Felipe VI, who on Tuesday lambasted the "irresponsible behaviour" of the Catalan leaders. The Catalan government said that around 2.26 million of the region's 5.34 million voters were able to cast their vote on Sunday.
In his televised address to the nation, the king said the Catalan leaders who organised the referendum showed their "disrespect to the powers of the state".
The king's speech was a response to the thousands of Catalan residents that hit the streets to protest the violent crackdown inflicted over the weekend by Spanish authorities attempting to block the vote, according to the outlet.
Puigdemont warned that if the Spanish government attempted to intervene and take control of Catalonia's government, it would be "an error which changes everything".
Protestors, many of them students, waved the Catalan independence flag Monday and held up signs demanding more democracy outside the headquarters of the Spanish police in Barcelona.
