Twitter users who broke an embargo on announcing Ryan Giggs as the footballer who took out a super-injuction to protect his identity for his part in an affair could be brought to justice.

Tony Wang, Twitter's new European boss, said he will hand over information of the users to authorities should he be legally asked to do so, going on to say people who had done 'bad things' will have to defend themselves.

Giggs' lawyers have filed court papers against Twitter and a number of its users after it was revealed on the social networking site that Giggs was having an affair with Imogen Thomas.

"Platforms have a responsibility, not to defend that user but to protect that user's right to defend him or herself," Mr Wang said responding to a question from BBC News at the e-G8 forum in Paris.

Whilst Mr Wang would not comment on the case directly he did say that Twitter would have no choice but to adhere to local laws and thus hand over users details.

"Let them exercise their own legal rights under their own jurisdiction, whether that is a motion to quash the order or to oppose it or do a number of other things to defend themselves," he continued, saying users would be notified if this was the case.
