Mexico's president given George Orwell's 1984 by the Queen
An unusual present from the Queen. Felipe Calderon was presented with a first edition during his visit to Buckinham Palace a few days ago.
A Palace spokeswoman said: "Apparently the president really admires George Orwell."
The 1949 book was boxed in leather by the bindery at Windsor.
Mr Calderon also received the traditional present given to guests - framed photographs of the Queen and the Duke of Edinburgh.
The president's wife Margarita Zavala received a small silver box with EIIR inscribed in gold on the lid.
The Queen received a Maque tray from Michoacan, the Mexican state from which the president comes. Philip received a wooden Olinala chest.
The exchange of gifts between rulers is a long-standing custom. In 1520 Henry VIII and Francis I of France exchanged gifts at the Field of Cloth of Gold in northern France.
