Felipe Gonzalez, former prime minister of Spain, has gone to Venezuela in order help the troubled leaders of the right wing opposition party win their freedom back after being arrested by the Maduro administration.

Arriving in Venezuela from Colombia on Sunday, Gonzalez plans on lending his aid to lawyers defending imprisoned opposition leader Leopoldo Lopez as well as Caracas mayor Antonio Ledezma, who is currently under house arrest.

In May, Lopez announced via a smuggled video that he would go on a hunger strike.

As reported by the Associated Press, Gonzalez, who has the distinction of being the the longest-serving Prime Minister of Spain, was greeted by members of the two men's families.

Lopez has been used as a kind of political pawn since his arrest. In January President Maduro hinted that he would send Lopez to the United States, if Washington released Oscar Lopez Rivera, a man who was convicted in 1981 of seditious conspiracy for trying to secure Puerto Rican independence.

Maduro has criticized Gonzalez for announcing that he would get involved with the case against Lopez, who is jailed on charges related to his role in leading protests against Venezuela's socialist administration in February of 2014.

Venezuela's Foreign Minister Elías Jaua has stated that Gonzalez is not welcome in the socialist country. As reported by the BBC, the Venezuelan Congress has classified Gonzalez as a "persona non grata."

Recently ex-presidents from Colombia as well as Bolivia have made trips to Venezuela in order to offer their support to the imprisoned politicians.

Harvard-educated Lopez, who is married to former television host and current human rights activist Lilian Tintori, has been out of the public eye since he stopped eating and his attorneys say that he has lost a lot of weight.

La Razon reported 26 other opposition members have joined the hunger strike. They do it in solidarity with Lopez and opposition leader Daniel Ceballos.

"Today the health of our political prisoners is very delicate," said Lopez's wife. Juan Carlos Gutierrez, Ceballos' attorney, confirmed her claims, adding that his client's health "is deteriorating quickly. I'm going with a doctor to evaluate him."
