Mohamed ElBaradei, former head of the UN's nuclear watchdog, has accused Egypt's government of being behind the publication of private photographs of his daughter in an attempted smear.ElBaradei, a potential presidential candidate in the coming elections, said the regime was leading a defamation campaign against him. Some Egyptian newspapers have published photographs of ElBaradei's daughter Laila dressed in swimming costumes and at an event in which alcohol was served.The pictures, apparently taken from her Facebook profile, were posted on the social networking site under the title 'ElBaradei's Family Secrets'.Commenting on the publication of personal photographs for his family on Facebook, ElBaradei said this "demonstrates the necessity of the demands for change we advocate because it is the only way to bring about democracy and reform".
