NEWS website BuzzFeed suffered a legal setback today over the scope of evidence due to be given by a former British spy who prepared a dossier on alleged links between Donald Trump and Russia.

Russian businessman Aleksej Gubarev is suing BuzzFeed in the United States after it published the entirety of the dossier, which includes several documents produced by former MI6 agent Christopher Steele or his company Orbis Business Intelligence.

The dossier alleges that Mr Gubarev’s companies XBT and Webzilla “had been using botnets and porn traffic to transmit viruses, plant bugs, steal data and conduct ‘alerting operations’ against the Democratic Party leadership.”
