Question to the Home Office:

To ask the Secretary of State for the Home Department, how many referrals her Department's Counter-Terrorism Referrals Unit has made to (a) Facebook, (b) Twitter, (c) Google and Youtube and (d) other websites or service providers in each of the last three years.

The Counter Terrorism Internet Referral Unit (CTIRU) is a police unit, based in the Met but with a national function. This unit is not able to release data on referrals made to specific companies as this may provide terrorist groups with useful information. Since its creation in 2010, CTIRU has secured the removal of more than 75,000 pieces of terrorist and extremist content.
