UK Demands Answers from China Over Embassy Blueprint Redactions Amid Espionage Fears

Angela Rayner, the Housing Secretary, has given China a two-week deadline to explain the redactions in the blueprints for its planned "mega-embassy" in London. The redactions, which include basement areas, have raised concerns that these spaces could be used for espionage. Rayner, responsible for deciding whether the controversial project at Royal Mint Court can proceed, has written to China demanding clarification after certain areas on the submitted floor plans were obscured. This action follows growing apprehension that the new embassy complex might become a center for covert activities in the capital.

The primary concern revolves around the potential use of basement rooms, which some have described as "spy dungeons." Rayner's demands are detailed in an update from her department sent to the planning consultancy representing the Chinese embassy. This intervention suggests a possible change in the government's approach to the sensitive application. Despite direct lobbying from China's premier, Sir Keir Starmer has so far refrained from intervening, even as the United States pressures the UK to block the project due to security concerns.

Rayner's letter, sent on Wednesday, was also addressed to the Home Secretary, the Foreign Secretary, local council officials, and the Metropolitan Police. It specifically requests that Beijing explain the redactions in the embassy plans, including a proposed basement "master plan" featuring anonymous rooms and a tunnel previously identified as a potential "modern-day dungeon" for spies. One diagram includes a note stating that the drawing has been redacted for security reasons. The letter also highlights that details of two buildings, the Cultural Exchange Building and Embassy House, both containing basements, have been obscured. Rayner's correspondence further asks for representations on whether she can make a "lawful determination" on planning permission given the redacted nature of the plans.

This development is likely to revive widespread concern about the proposed embassy. Critics have repeatedly warned that it could pose a risk to UK national security. The US is believed to have urged Britain to reject the proposals due to their proximity to sensitive data hubs near key financial districts. Sir Iain Duncan Smith, a former Conservative leader, wrote to Rayner last month, reiterating these concerns and arguing that it would be "inappropriate" to approve the application until a plan is in place to address such a "serious matter." The planned Chinese embassy at Royal Mint Court, near the Tower of London, has been involved in a long-running planning dispute, with Rayner calling in the decision for review last year.
