The Venezuelan opposition on Sunday called to scale up the street protests against the government of president Nicolas Maduro, claiming that June will be a definitive month, and announced that the fundamental objective will be to block the Constituent Assembly.

"It is very important that the country knows that the Democratic Unity take up June as a definitive month," the vice-president of the National Assembly, Freddy Guevara, said at a press conference on behalf of the opposition alliance, Democratic Unity Roundtable (MUD), and stressed that the Venezuelan people "have already spent 58 days on the streets."

"June is a key month in which the Venezuelan people will demonstrate their organization, their conviction and their commitment to a free Venezuela through a process of increasing the pressure against the dictatorship significantly," he added.

Guevara questioned the Constituent Assembly, which Maduro's government promotes as a way out of the country's crisis, and warned that if "this fraud is allowed to be established, Venezuela will be lost."

"Therefore, we have decided (...) to take this up as a fundamental objective, not only of the Unity but of all the people of Venezuela, to prevent that fraudulent process in the country," he said.

He urged the people to stay in the streets "despite repression, tiredness or hopelessness" as well as to be organized and ready "for an escalation, to increase the pressure."

"Given the seriousness of the process and the strength we have achieved in almost 60 days of resistance, the Democratic Unity tells our people that it is time to move forward," he added.

He also pointed out, without going into details, that they will, "in a matter of days" give the country a clear path that will push the government against the wall and will "block" the Constituent Assembly.

Venezuela has been facing protests by both the government and the opposition for two months, some of which have resulted in violence, leaving at least 59 dead, according to figures from the Prosecutor's Office.
