Overview

• New reports say suspect Christopher Berry was stopped at Heathrow in February 2023 with about £4,000 during a Schedule 3 port stop, six weeks before his arrest.
• Police confirmed a man in his thirties was stopped on 2 February 2023 under counter‑terror border powers, with devices seized that later linked Berry to parliamentary researcher Christopher Cash.
• Downing Street published witness statements from deputy national security adviser Matthew Collins, including an allegation of a 13‑hour tasking‑to‑report cycle involving Berry and Cash.
• Prosecutors had alleged Berry produced at least 34 reports for a handler known as “Alex,” with 10 assessed as prejudicial to UK national security, and that intelligence reached senior Chinese official Cai Qi.
• The Crown Prosecution Service dropped the case last month, both men deny wrongdoing, and the Intelligence and Security Committee has launched an investigation into the handling of classified material.
