Havana ? During her decade inside Cuba’s opposition, Aleida de las Mercedes Godinez was so trusted that a dissident shared her e-mail password and exile groups in the United States sent her money.

As government agent code named “Vilma,” Godinez had access to extensive information about the many opposition groups in the island’s largest dissident coalition, as well as the individual dissidents rounded up in March and tried weeks later.

Speaking with The Associated Press in her first interview with international media, Godinez provided a rare glimpse inside Castro’s intelligence network and demonstrated just how deeply loyal his agents were. Like many other agents who infiltrated the opposition, she came from a communist family long trusted by Castro.

“The opposition is finished, it has ended, it will never lift its head again,” Godinez declared. “The opposition will never flourish again — never!”

Monday’s interview with Godinez was the first in a series of government-organized interviews the agents are giving to the international media.

The families of some of the 75 dissidents who were quickly convicted and sentenced to prison earlier this month acknowledged the severe damage caused by the undercover agents, particularly Godinez.

She was a key leader of a coalition called the Assembly for the Promotion of Civil Society and had allied with the dissidents since 1994, sometimes working even as an independent journalist.

The dissidents were convicted of working with U.S. diplomats to subvert Fidel Castro’s government and were given sentences ranging from six to 28 years. The dissidents and the United States have denied the accusations.

Dissident economist Marta Beatriz Roque’s family said Godinez’s surprise testimony was key to her conviction and 20-year prison sentence. Godinez said Roque even gave her the log-on name and password to access her e-mails.

Cuban undercover agent Aleida de Las Mercedes Godinez, 49, talks with the international press at the press center in Havana. Godinez, who is credited with providing some of the most damaging evidence used during the recent trials of scores of dissidents, declared this week that the island's opposition movement had been permanently disabled.

Godinez said she never felt any remorse or sorrow for her work even though she worked with some dissidents for years. “Marta Beatriz was an objective of my mission,” she said. “I could never be friends with a counterrevolutionary.”

Godinez said Roque, also a leading member of the Assembly for the Promotion of Civil Society, handled as much as $5,000 every month from various groups in the United States that were funded by the U.S. Agency for International Development.

The USAID Cuba program has given more than $20 million to U.S. groups working with the opposition on the communist-run island since 1996 to bring about a peaceful transition to democracy.

Godinez, a former math teacher, said she received about $700 a month from U.S. organizations as head of the National Independent Workers Union of Cuba. A new laptop computer was sent to her last year by a Cuban-American organization in Miami.

The agents’ superiors evidently allowed them all to keep the money and equipment they received from U.S. groups.

Godinez would not say what she will do next. “That’s secret,” she said with a smile. “But I can say that I will keep working for the revolution.”
