Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, pursuant to the Answer of 17 July 2025 to Question 66464 on Submarine Telegraph Act 1885, by when will she have considered whether existing penalties and definitions remain fit for purpose to address modern threats.

Existing penalties for acts of sabotage to submarine cables are significant. Under the National Security Act (NSA) 2023 the sabotage offence carries a maximum penalty of life in prison or a fine, or both, where the activity is conducted for, on behalf of, or for the benefit of a foreign power.

Where the foreign power condition cannot be met, the offence under the NSA does not apply, and the penalties available under the Submarine Telegraph Act 1885 are more limited. This is under review.
