Spain's El Pais apologises for false Hugo Chavez photo

Spain's El Pais newspaper has apologised after publishing a photo of Venezuelan President Hugo Chavez which it said has turned out to be a fake.

The photo shows a man in hospital with a tube in his mouth and was printed on the front page with the headline: "the secret of Chavez's illness".

The Venezuelan government called the photo "grotesque".

Mr Chavez has not been seen in public since undergoing treatment for cancer in Cuba last month.

El Pais has withdrawn the photo from its website and collected copies of the first edition of Thursday's paper from newsstands, the BBC's Tom Burridge reports from Madrid.

The paper said in a statement that it had obtained the image from a news agency but that it had not been able to independently verify the date, location or circumstances of the photo.

The photo had stayed on El Pais's website for around half an hour, it said.

The paper has now opened an investigation into "the mistakes that may have been committed in the verification of the photograph".

Mr Chavez's illness has become a political issue in Venezuela, with the opposition criticising the president's prolonged absence from the country.

Mr Chavez won re-election in October, but his 10 January inauguration ceremony has been indefinitely postponed because of his illness, in a move that forced the Supreme Court to decide on the legality of the situation.
