Russian Interference in UK Politics

I am familiar with the study that my hon. Friend is referring to, but I would just say that it is very narrowly focused. There is also evidence of more than 13,000 bot accounts on Twitter that were believed to be linked to Russia and were deleted very shortly after the referendum. There is a lot that we do not know about this matter, and we need the tech companies to co-operate with us fully so that we understand the scale of it.
