Madrid - Prominent political, social and cultural figures in Spain and elsewhere have called on U.S. President, Barack Obama, to totally lift the U.S. blockade that has been imposed on Cuba for more than 50 years.

Names such as Spaniard, Federico Mayor Zaragoza, former Director-General of UNESCO; and the Argentine, Adolfo Perez Esquivel, a Nobel Peace Prizewinner (1980), are among the signatories of a letter sent to Obama demanding the end of the genocidal policy.

The letter to the U.S. president is part of a campaign called 'For a 2016 without the Blockade on Cuba', Lois Perez, coordinator of the initiative, reported today in a news release.

'Mr. President, we ask you, as a Nobel Peace Prizewinner, that you, in 2016, lift the inhumane blockade on the Republic of Cuba,' the text says.

In the letter, the signatories urge the president to end the blockade against the island, with the aim of making the entire American continent a land of peace, brotherhood and free from wars, as Bolivar, Washington and Jose Marti dreamed.'

'Obama's visit to Cuba and his talks with President Raul Castro, encourage us to think that this old dream, of the Cuban people and its government, as well as across the continent and the whole of humanity, could be a wish come true,' they added.

After expressing satisfaction for the restoration of the diplomatic relations between the two countries, they encourage Obama to take the necessary and decisive steps to end the economic, commercial and financial blockade imposed on the Republic of Cuba.

Some few hours before the United Nations General Assembly rules, for the 25th consecutive year, against the unilateral sanctions, the letter reminds the U.S. president of the 2015 vote, when 191 of 193 countries demanded the elimination of the hostile policy.

In addition to the mentioned figures, singer and actress Pepa Flores, singer-songwriters Luis Eduardo Aute and Luis Pastor, poet Luis Garcia Montero, writer and playwright Alfonso Sastre, actor Hector Alterio and novelist Belen Gopegui, signed the letter to Obama.

Others such as United Left leader, Alberto Garzón; General Secretary of the Communist Party of Spain, Jose Luis Centella and Deputy Secretary of International Relations and Podemos, Paul Bustinduy also signed.

In parallel with this campaign, several regional parliaments in Spain rallied unanimously against the blockade, including Galicia, the Basque Country, the Canary Islands and Andalusia, as well as 30 municipalities, councils, county councils and town councils.
