Article: In 2003 the paper was accused of racism by the Government over its criticisms of what it perceived as the "open door" policy on immigration. The attacks came from the Prime Minister's press spokesman Alastair Campbell and the Home Secretary David Blunkett (later a Sun columnist). The paper rebutted the claim, believing that it was not racist to suggest that a "tide" of unchecked illegal immigrants was increasing the risk of terrorist attacks and infectious diseases. It did not help its argument by publishing a front page story on 4 July 2003, under the headline "Swan Bake", which claimed that asylum seekers were slaughtering and eating swans. It later proved to have no basis in fact. Subsequently The Sun published a follow-up headlined "Now they're after our fish!". Following a Press Complaints Commission adjudication a "clarification" was eventually printed, on page 41. In 2005 The Sun published photographs of Prince Harry sporting a Nazi costume to a fancy dress party. The photographs caused outrage across the world and Clarence House was forced to issue a statement in response apologising for any offence or embarrassment caused.
