Cambridge Analytica’s London offices will finally be searched by the UK's Information Commissioner’s Office, following a marathon week of arguing inside and outside court.

Woolwich Crown Court, sitting in the capital's Royal Courts of Justice for the occasion, granted the warrant after a five-hour hearing. The ICO, as the UK’s data protection regulator, wants to raid Cambridge Analytica’s premises to see whether the controversial consultancy still has copies of millions of people’s Facebook data, as allegedly slurped from the platform without users’ explicit consent.
