Rough translation of a news brief regarding Panama trip:
"The Princes of Asturias Felipe de Borbón and Letizia Ortiz, traveled today to Panama to attend the inauguration of the president-elect of that country, Martín Torrijos, the Spanish Royal House informed. In agreement with the official agenda, the couple will arrive in the capital of the Central American country on Tuesday morning, where they will be received by outgoing president Mireya Moscoso, and later they will meet with Torrijos. At the Spanish embassy, the princes will offer a lunch to personalities of the political, economic, and cultural life of Panama, they will later make a visit to the Canal and at night they will attend a supper offered by Moscoso."
As far as I know, the inauguration itself is on Wednesday, after which they will hold a reception for the Spanish colony in Panama before returning to Spain that same evening.
