NATIONAL SECURITY

The construction of the new Chinese “super-embassy” in the heart of London has been a long-running saga, its development plans shrouded in secrecy. Back in 2018, Beijing bought the Royal Mint site – an act whose symbolism was not lost on most Britons – for £255m. Assurances were given that the building would be used for normal diplomatic functions. But when the plans were released, they included a vast basement complex with no obvious purpose. Curiously, the details of the basement were redacted.

The true extent of Beijing’s plan has now been revealed. There will be 208 underground rooms, including a hidden chamber equipped with hot-air extraction systems, one metre away from Britain’s most sensitive communication cables, which transmit financial data to and from the City of London, as well as messaging traffic for millions of internet users.

Even before these revelations came to light, the Chinese plan came with obvious security risks: last year MI5 issued an “espionage alert” about Beijing’s spies targeting MPs and parliamentary staff “at scale”, while the US told Britain to reject the proposal on the grounds that it could effectively become a den of spies working against Western interests.

Planning permission has not yet been granted, but it is widely expected that Sir Keir Starmer will approve the proposal ahead of his visit to China later this month. For many in Britain, the obvious question should loom: why?

Labour’s 2024 general election manifesto promised an audit of Britain’s relationship with China. In the end, only two paragraphs of it were published, in the National Security Strategy. And, as is publicly known, the failure last year to prosecute Christopher Cash and Christopher Berry, two alleged spies for China, was because the UK Government was not prepared to provide witnesses willing to describe China as “an enemy”.

Britain is in the economic doldrums, and Starmer is desperately seeking more direct investment for his growth plans. China has slowly been buying up Britain, purchasing UK gilts as well as companies. This leaves the UK vulnerable to pressure from Beijing, which has a record of using debt as leverage. The PM clearly believes Britain needs to be on good terms with China.

However, that shouldn’t stop him quizzing Beijing. If there is nothing to see, why was so much of the plan redacted? Why does a foreign embassy need 208 rooms underground? Why demolish and rebuild the outer basement wall of the secret chamber, directly beside the fibre-optic cables that carry information critical to Britain’s national security and prosperity? And if the embassy is built, what does Britain gain?

These questions need to be satisfactorily answered before the green light is given to build a Chinese super-embassy in London.
