Havana - Cuban President Miguel Diaz-Canel said Monday the May 1 parade will be a scene to denounce the US aggressiveness against Venezuela and Nicaragua and demand the rapid release of Luiz Inacio Lula da Silva.

' All over Cuba's squares, we meet on May 1st to denounce the blockade, the aggressive US policy against Cuba, Venezuela and Nicaragua, to demand Lula's release, to ratify that: Nobody gives up here', wrote the Cuban leader in Twitter.

This parade will be held a few days after the 21st Congress of the Cuban Workers Union (CTC), which in its final statement condemned the Helms Burton Act as an expression of Whashington's annexationist and meddling attempts against Cuba.

The document urged to demand the end of the economic, commercial and financial blockade imposed on Cuba for more than half a century and the return of the illegally occupied territory at the Guantanamo Naval Base.

The delegates demanded the White House close the episode of harassment against the Venezuelan Revolution led by President, Nicolas Maduro, while ratifying their support for the Venezuelan people.

The final statement also called on trade unions to demand the release of former Brazilian President Luiz Inacio Lula da Silva, a political prisoner of neoliberalism in the region.
