The government does not hold this information

A robust law enforcement response is a fundamental part of the government's drug strategy and we are taking coordinated action to tackle illegal drugs alongside associated criminal activity. Law enforcement agencies continue to work with internet service providers to shut down UK-based websites found to be committing offences such as selling drugs controlled under the Misuse of Drugs Act 1971.

The government has been clear that more needs to be done to tackle online harms, including sale of illegal goods. That is why the Government published the Online Harms White Paper, which sets out our plans for world-leading legislation to make the UK the safest place in the world to be online and hold companies to account for tackling a wide range of online harms.

On 7-8 November the Home Secretary co-hosted a Hackathon with Microsoft and the WePROTECT Global Alliance. Leading companies, including Facebook and Snapchat, worked to develop a prototype tool to detect online grooming, which will be provided licence free to small and medium companies worldwide.

The Home Secretary met with the senior leadership of Facebook, Snapchat and other technology companies to urge them to promote the use of the new prototype to tackle potential instances of online grooming.

Since the Hackathon, the Home Office have been engaging with technology companies, including Facebook and Snapchat, and discussing how to fulfil the Home Secretary’s priority asks of the technology industry, as outlined in his speech at the NSPCC on 3 September. While progress has been made on detection and disruption of online grooming, on these platforms and others, significant challenges remain. We continue to work with companies to drive greater transparency on online grooming and foster greater sharing of best practice and technology between companies.

The Home Office is also engaging with key industry stakeholders on the Online Harms White Paper. The White Paper will set out a range of legislative and non-legislative measures detailing how we will tackle online harms and set clear responsibilities for tech companies to keep UK citizens safe online. Protecting children from abuse and exploitation online will be a central component of the White Paper.

The Secretary of State for the Home Department is not responsible for investigating data protection breaches. This is a matter for the Information Commissioner as the regulator. On 19 March, the Secretary of State for Digital, Culture, Media and Sport indicated that the Information Commissioner is looking at whether Facebook data was acquired and used illegally.

The Secretary of State for the Home Department has not had any recent discussions with her counterpart in the US administration regarding (a) Cambridge Analytica, (b) Strategic Communications Laboratories, (c) Global Science Research and (d) Aleksandr Kogan in obtaining personal data from Facebook.

The allegations concerning Cambridge Analytica are currently under investigation by the Information Commissioner.

The Secretary of State for the Home Department has not met with representatives of Facebook to discuss the potential security breach of UK citizens’ data.
