Angela Rayner has given China two weeks to explain why parts of its plans for a new mega-embassy in London are redacted.
The deputy prime minister’s Ministry of Housing, Communities and Local Government sent a letter asking for further information and requested a response by 20 August, the understands.
Beijing’s plans for the new embassy have sparked fears its location – very near London’s financial district – could pose an espionage risk. Residents nearby also fear it would pose a security risk to them and attract large protests.
The has contacted the Chinese embassy in London for comment.
A final planning decision on the controversial plans will be made by 9 September, the understands.
In a letter seen by the PA news agency, Rayner, who as housing secretary is responsible for overseeing planning matters, asks planning consultants representing the Chinese embassy to explain why drawings of the planned site are blacked out.
The Home Office and the Foreign Office also received copies of the letter.
It notes that the Home Office requested a new “hard perimeter” be placed around the embassy site, to prevent “unregulated public access”, and says this could require a further planning application.
There are concerns, held by some opponents, that the Royal Mint Court site could allow China to infiltrate the UK’s financial system by tapping into fibre optic cables carrying sensitive data for firms in the City of London.
Pro-democracy campaigners from Hong Kong also fear Beijing could use the huge embassy to harass political opponents and even detain them. Last month, the UK condemned cash offers from Hong Kong authorities for people who help in the arrest of pro-democracy activists living in Britain.
Alicia Kearns, the shadow national security minister, said: “No surprises here – Labour’s rush to appease Xi Jinping’s demands for a new embassy demonstrated a complacency when it came to keeping our people safe. Having deluded themselves for so long, they’ve recognised we were right to be vigilant.”
Responding to security concerns earlier this week, the Chinese embassy told the it was “committed to promoting understanding and the friendship between the Chinese and British peoples and the development of mutually beneficial cooperation between the two countries. Building the new embassy would help us better perform such responsibilities”.
China bought the old Royal Mint Court for £255m in 2018. At 20,000 square metres, the complex will be the biggest embassy in Europe if it goes ahead.
The plan involves a cultural centre and housing for 200 staff, but in the basement, behind security doors, there are also rooms with no identified use on the plans.
Beijing’s application for the embassy had previously been rejected by Tower Hamlets Council in 2022 over safety and security concerns.
It resubmitted an identical application in August 2024, one month after Labour came to power.
On 23 August, Sir Keir Starmer phoned Chinese President Xi Jinping for their first talks. Sir Keir confirmed afterwards that Xi had raised the embassy issue.
Rayner has since exercised her power to take the matter out of the council’s hands amid attempts by the government to engage with China after a cooling of relations during the final years of Conservative Party rule.
Senior ministers have signalled they are in favour if minor adjustments are made to the plan.
