Unflattering pictures of German Chancellor Angela Merkel in a British newspaper have sparked a backlash from the German government and media.
Angela Merkel is on a two-week holiday in the gulf of Naples
The Sun printed photos of Mrs Merkel on holiday taken from behind while changing into her bathing costume.
A government spokesman accused the tabloid of voyeurism and said the chancellor had a right to privacy.
There is little the British tabloid press likes more than the chance to have a go at Germany and the Germans.
Mrs Merkel is the latest target. The Sun printed the photos under one of its trademark puns: "I'm Big in the Bumdestag".
A German government spokesman, Thomas Steg, said: "This is certainly not traditional British courtesy", but he ruled out any legal action against The Sun.
The reaction in parts of the German media has been fiercer.
Bild - itself a sort of German version of The Sun - said: "The English are mocking our Chancellor." And it asked: "Where does this hatred come from?"
It reprinted a page from The Sun - but reduced in size and with a big red square partially covering a photo of Chancellor Merkel.
The Sun pictures of Angela Merkel look like the preliminary round in what is likely to be a series of British tabloid stories mocking the Germans in the run-up to the World Cup, being held in Germany this summer, most referring one way or another to World War II.
