The United Socialist Party of Venezuela (Partido Socialista Unido de Venezuela, PSUV) is a left wing political party in Venezuela that is in the process of being founded. It was initiated by Venezuelan president Hugo Chávez after he won the Venezuelan presidential election of 2006 in order to merge all parties which support the Bolivarian Revolution.
On 18 December 2006, the Minister of Communication and Information Willian Lara announced the preparation of a letter addressed to the National Electoral Council, regarding the proposal to formally disband the Fifth Republic Movement. Chávez has stressed the need for a single, united Bolivarian party.
The party held its founding congress in early 2008.
Of the twenty-four parties which supported Chávez in the 2006 presidential election, eleven are in the process of joining PSUV. On March 7 2007, Chávez presented a phased plan for founding the new party until November 2007.
For Social Democracy, Fatherland for All and the Communist Party of Venezuela have stated they will wait until PSUV has been founded and decide their membership in the new party based on its program.
On March 18 2007, Chávez declared in his programme Aló Presidente
that he had "opened the doors for Podemos, Patria Para Todos, and the Venezuelan Communist Party so that if they want to go away, they may do so and leave us in peace". He declared that in his opinion those parties are almost in the opposition and added that they had to choose well the way to go, "in silence, hugging us or throwing stones".
Patria Para Todos decided at its annual congress from April 10 to April 11 not to dissolve, while re-affirming its support for Chavez and the Bolivarian Revolution.
