Special counsel investigators meet MI6 man

A former British spy who compiled a dossier with allegations that Russia helped Donald Trump in the 2016 US presidential election has met with investigators working for the special counsel on the case, a source familiar with the contact says.

Christopher Steele, a former senior operative for MI6, the British foreign intelligence agency, met representatives of special counsel Robert Mueller's team "recently," said the source, who declined to provide further details.

A spokesman for Mueller declined comment.

While President Trump and some of his supporters have dismissed the dossier as "fake news", two sources familiar with Mueller's probe and a Senate Intelligence Committee investigation of suspected Russian meddling in the election said on Thursday that investigators have not dismissed it.

Russia has repeatedly denied any interference in last November's election won by businessman Trump, a Republican.
