Civil rights lawyers are to fight a move by the US government to sacrifice the privacy of Twitter users linked to WikiLeaks.
Officials have ordered the social media firm to disclose confidential data on the whistleblowing organisation and three of its clients, amongst them Icelandic MP Birgitta Jonsdottir, as part of their ongoing campaign against the site.
It raises wider concerns over individuals rights to privacy in the digital age however.
Embarrassed by a series of leaks the US has set up a secret grand jury to investigate whether a court case can be brought against Julian Assange, a move which led to Twitter being ordered to disclose the data it held.
A court hearing held to decide whether the move should be declared unlawful broke up without any ruling from the judge.
