A Chinese mega embassy in London could bring security advantages, despite concerns from opponents, according to the prime minister's official spokesperson. The spokesperson highlighted the benefit of consolidating seven Chinese sites around the capital, as the decision on planning permission has been postponed for a third time into the new year. Some worry that the mega embassy could be a hub for espionage, but the government is expected to approve it on January 20th. This delay aims to allow more time for consultation among all stakeholders. In a letter to an opposing group, the Interparliamentary Alliance on China, the home secretary and foreign secretary addressed national security concerns, stating that China has agreed to move all its accredited diplomats to a single site if approved. The spokesperson emphasized that consolidation would enhance security for the UK. The Chinese embassy, if built, would be the largest in Europe, accommodating 200 staff, offices, and a large basement. Its proximity to fibre optic cables carrying sensitive data adds to security suspicions. Redacted planning documents have raised further questions. The former deputy prime minister, Angela Rayner, gave China a two-week deadline to explain the purpose of certain rooms, which officials now seem satisfied with. The Chinese Embassy claims the complex will boost cooperation, but officials argue that objections are unjustified. Prime Minister Sir Keir Starmer acknowledged the delicate balance in UK-China relations, recognizing China's influence in technology, trade, and global governance while addressing national security threats. The head of MI5 has described Chinese state actors as a daily threat, and the security service issued an alert about Chinese profiles on LinkedIn targeting MPs and staff. Shadow housing secretary Sir James Cleverly accused Labour of rushing planning approval without proper scrutiny due to a lack of courage to confront China. He criticized the suppression of security service criticism and called for full, unredacted drawings to be made available.
