Prince Felipe, the heir of the Spanish crown, is likely to hold an informal talk with President Hugo Chávez, during the inauguration of Argentinean president elect Cristina Kirchner next December 10, diplomatic sources said Thursday.

It would be a "fortuitous meeting" with "an informal nature" they may hold on the sidelines of the inauguration in Buenos Aires, the source said.

Chávez and the Spanish government are going through a crisis, following a verbal clash with Spanish King Juan Carlos I, who asked Chávez to shut up during the 17th Ibero-American Summit, held in Chile.

On Monday, Spanish Foreign Minister Miguel Angel Moratinos congratulated the Venezuelan people for their "democratic maturity," following a referendum on December 2 where Chávez's intended changes to the Constitution were rejected, AFP reported.

On Wednesday, Chávez labeled as "a good sign" the congratulations of the Spanish government.

"I was asked to talk to the Prince of Asturias in Buenos Aires, as he is going to deliver a personal message from the King. I am going to talk to him because I am a gentleman," Chávez said.
