Libyan leader's son Seif al-Islam said in an interview for Spanish magazine Tiempo de Hoy he to have played a mayor role in the negotiations related to the release of Bulgarian medics who had been previously sentenced to life in prison in Libya.

Seif al-Islam told the magazine as quoted by Bulgarian National Radio that he was the person who made the scheme which solved the problem.

When asked about the role of the French president's wife Cecilia Sarkozy, Seif al-Islam said that the French first lady had luck because many other top level officials had tried before her to release the medics.

Cecilia Sarkozy became her husband's personal ambassador in July during the final phase of negotiations for the medics' release.

When asked what France offered more than the other countries, Al Islam said the difference was hundreds of millions of euro in aid to Libyan healthcare system.

Al Islam confessed that the case with the Bulgarian medics was an immoral ''game'', the rules of which were defined by Europeans who continue to pay the price for it. He said that Libya blackmailed Europe but Europeans also blackmailed the Libyans.

The six Bulgarian medics, who had been sentenced to life-in-prison for intentionally infecting more than 400 children in Libya with HIV, were released and pardoned by Bulgarian President Georgi Purvanov immediately after their return to Bulgaria. The negotiations for the release involved many institutions and provoked reactions worldwide.
