A row has broken out between Wikileaks and one of the newspapers it collaborated with to leak US diplomatic cables. The whistle-blowing group said unredacted versions of the 251,000 diplomatic cables had been leaked on the internet. Wikileaks blamed the disclosure on the Guardian newspaper and said it had started legal action against the paper. The newspaper has strongly denied the claims, blaming a "security breach". In a short statement on Twitter, Wikileaks said: "A Guardian journalist has, in a previously undetected act of gross negligence or malice... disclosed top secret decryption passwords to the entire, unredacted, Wikileaks Cablegate archive.

It has been one long battle for WikiLeaks merely to exist on the Internet since it started publishing the U.S. diplomatic cables. The cat-and-mouse game that it has had to play to retain an accessible address in cyberspace is the result of a virulent attack launched by right-wing lawmakers in America and their supporters, and commercial entities such as Amazon, which caved in to the pressure. But more fundamentally, the WikiLeaks saga represents the acid test for free speech. With each tranche of documents published online, the world is witnessing the total loss of dominance of secretive governments over information.
