France\'s Foreign Minister Laurent Fabius denied a \"rumour\" in a newspaper report claiming that he may have a Swiss bank account, as the French government struggles to deal with a scandal over undeclared foreign bank holdings. \"I absolutely deny the rumour, published in the Monday April 8 edition of Liberation, claiming I have a bank account in Switzerland,\" Fabius wrote in a statement. There is no \"substance or foundation\" to the report, he added. Fabius also announced that he would pursue legal action to \"stop the diffusion of this false and slanderous information\". The headline in Liberation read: \"A possible Fabius affair petrifies the Elysee\", referring to the French president\'s office. In the long article there are no facts showing that France\'s top diplomat has an undeclared foreign bank account, it simply stresses that the Mediapart news website \"is exploring this line\" of investigation. Mediapart journalist Fabrice Arfi told Liberation that the only news Mediapart had \"is what is published on our website\". It was Mediapart that broke the story about former budget minister Jerome Cahuzac having an undeclared bank account in Switzerland. President Francois Hollande\'s government has been shaken by the scandal which erupted Tuesday after Cahuzac -- once in charge of tackling tax evasion -- admitted to investigators that he had a foreign account containing some 600,000 euros ($770,000).
