Question to the Cabinet Office:

To ask His Majesty's Government what assessment they have made to determine whether the app TikTok is being used on any government-issued mobile devices; and whether they consider the presence of the app on government phones to be a threat to national security.

The Cabinet Office maintains a constant dialogue with departments on their security and data concerns. Departments are required to manage all applications and services on their networks, taking into account security and data protection risks.

Specific information on the use of any individual application is not routinely held centrally.

With regards to the threat to national security His Majesty’s Government does not comment on these matters.
