A former parliamentary staffer has been arrested under computer hacking legislation, Commons Speaker Sir Lindsay Hoyle announced to MPs on Monday afternoon.

In a statement delivered at the start of Commons business, Sir Lindsay revealed that an individual had been detained under the Computer Misuse Act 1990. The Speaker provided the information to the House as part of his opening remarks for the day's proceedings.

The Computer Misuse Act 1990 is the primary legislation in the UK that addresses unauthorized access to computer systems and data. Offenses under the act can range from basic unauthorized access to more serious charges involving intent to commit further crimes or impair computer operations.

No additional details were immediately provided about the nature of the alleged offenses, the identity of the individual, or the specific circumstances that led to the arrest. The Speaker's statement was brief and focused on informing MPs of the development.

The announcement comes as Parliament continues to grapple with cybersecurity concerns and the protection of sensitive government systems and information.
