The Russian jury has been revealed to have Periscope themselves as they deliberated on the songs in the first semi final.

The Periscope shows the jurors during the performances from the Netherlands and Armenia. During the Periscope a juror shows a blank score sheet of all of the countries in the semi final. However it is clear to see that the juror is voting up the Netherlands, but voting down Moldova and Hungary.

Questions have been raised as to whether the Russian jury were allowed to stream themselves during the decision making process. Furthermore, the way in which the jurors are carrying out the process of judging the songs is also question with one juror seen dancing during a performance.

Watch the periscope session here.
