Johnson Suggests Mandelson Linked to China Spy Controversy

Published: 14 October 2025. The English Chronicle Desk. The English Chronicle Online.

Boris Johnson has raised fresh allegations suggesting Lord Mandelson may be connected to the ongoing China spying row that has embroiled the Labour Party, claiming that the UK is increasingly “being pushed around by China” under the current Government.

Speaking to the Daily T podcast, the former prime minister argued that a series of what he described as “inexplicable” decisions since Labour came to power, including the Government’s refusal to designate China as a security threat and the controversial Beijing-backed agreement over the Chagos Islands, point to a troubling pattern.

“I think there’s something very wrong going on here,” Johnson said. “When you feed in what happened with Chagos, it all does look like a bit of a pattern, because the Chagos decision is so bad, it’s virtually inexplicable, except in the context of some kind of pressure from China, who are very close to Mauritius.”

Johnson’s remarks specifically referenced Lord Mandelson, the former ambassador to the United States who was sacked last month following revelations about his links to Jeffrey Epstein and other controversies. The former prime minister pointed to Mandelson’s relationship with Jonathan Powell, the current Prime Minister’s national security adviser, who has come under scrutiny for his alleged role in the collapse of a high-profile espionage case involving suspected Chinese spies.

The case in question involved Christopher Cash, who had worked for Tory MPs, and Christopher Berry, a teacher. Both were arrested in March 2023 on suspicion of passing sensitive intelligence to Beijing. However, the trial collapsed last month, raising questions from both the Conservative Party and security experts. Johnson described the collapse of the case as “making [my] government look absolutely squeaky clean and wonderful,” arguing that the legal process had been mishandled.

“I don’t know why they dropped this case,” Johnson said. “What I do know is that you don’t need all that rigmarole. If you’ve got people bang to rights, passing sensitive information to any foreign power, whoever they are, you can prosecute them. You can prosecute them. It’s nonsense.”

The scandal has prompted political figures such as Tory leader Kemi Badenoch to state that Powell “has questions to answer” regarding his role in the collapse of the espionage trial. While ministers insist that Powell was not involved in the substance or evidence of the case, critics argue that he may have failed to provide prosecutors with crucial intelligence needed to secure convictions.

Johnson went further, linking Mandelson and Powell directly to China. “There is a nexus of individuals… Mandy, Peter Mandelson was one. He is very closely connected to the current national security adviser, Jonathan Powell, who are close to China. I think there’s more to run on this. It’s a disaster because it makes us beholden and continually subject to Chinese pressure.”

A friend of Lord Mandelson dismissed Johnson’s claims as “media piffle,” emphasising that Mandelson had no personal or professional links to the Chinese government and had, in fact, taken a tough stance on China in previous public speeches, including his annual lecture at the Ditchley Foundation.

Nevertheless, questions about Mandelson’s relationship with China have been raised before. In 2021, he appeared on a remote video call alongside Li Keqiang, then the Chinese premier, in an event organised by the China Council for the Promotion of International Trade. Leaked minutes of the meeting reportedly included glowing remarks from Mandelson about China’s leadership and its ability to “prove [their critics] wrong.”

At the time, Mandelson was running his Global Counsel consultancy, which has had high-profile clients including TikTok, the social media platform banned from UK government devices over security concerns, and Shein, an online fashion retailer accused of using forced labour. Experts have suggested that the China Council for the Promotion of International Trade may act as a longstanding influence operation by the Chinese Communist Party aimed at co-opting Western businessmen. The event was attended by 20 senior European executives from major corporations including Airbus, AstraZeneca, Maersk, Nokia, Prudential, and Suez.

Mandelson subsequently resigned from Global Counsel to take up his ambassadorial role in February, only to be sacked last month following revelations about his personal connections to Jeffrey Epstein, a scandal that some say has undermined Sir Keir Starmer’s premiership. Johnson has argued that these controversies collectively illustrate a Government weakened under Labour leadership.

“He makes us all look like models of sleaze-free probity,” Johnson said. “The whole thing is disgraceful. We are in a state now where Britain looks very, very weak. We did nothing to help with the Palestine problem – that was Trump basically pushing; we did nothing to get those hostages back and it’s clear that we are now being pushed around by China.”

The former prime minister’s comments have reignited debate about the UK’s relationship with China and the handling of espionage and security threats. While the collapse of the espionage case has raised concerns across the political spectrum, Johnson’s direct linking of Mandelson to the issue adds a new layer of controversy, particularly given Mandelson’s former positions as business secretary, European commissioner, and diplomat.

Observers have noted that Johnson’s allegations, if substantiated, could have far-reaching consequences for both Labour’s credibility on national security and the UK’s diplomatic posture. The former prime minister suggested that failures to properly confront Chinese influence in areas such as Mauritius and intelligence operations could leave Britain vulnerable to external pressure, highlighting the perceived need for stronger oversight and accountability.

The controversy also intersects with broader discussions about governance, transparency, and the role of elite networks within UK politics. Mandelson, often described as a key figure within the Labour Party’s establishment, has long been a polarising figure in British public life. Johnson’s comments, whether politically motivated or rooted in genuine concern, underscore the scrutiny surrounding relationships between politicians, advisers, and foreign interests.

Security analysts have emphasised that regardless of Mandelson’s direct involvement, the UK must address weaknesses in intelligence handling and inter-agency coordination to prevent future collapses of sensitive cases. The combination of political missteps, high-profile resignations, and ongoing international pressures has created a climate of heightened scrutiny around both the Government and opposition figures.

As the story develops, attention is likely to remain on Lord Mandelson, Jonathan Powell, and the handling of UK-China relations. Johnson’s statements have already prompted responses from political allies and critics alike, with debates emerging over the boundaries between national security, diplomatic engagement, and political accountability.

While Lord Mandelson’s spokesperson has categorically denied any improper links to China, noting his track record of challenging the Chinese government on trade and security matters, the claims made by Johnson are likely to keep the controversy alive in the media and parliamentary discourse.

The broader implications of the China spying row, coupled with the Chagos Islands decision and other foreign policy issues cited by Johnson, have reignited questions about the UK’s global influence and the capacity of the current Government to respond decisively to international challenges. Analysts suggest that the combination of espionage scandals, diplomatic deals, and political intrigue may continue to dominate headlines and shape public perceptions of the Labour administration.

Ultimately, Johnson’s remarks represent a significant escalation in political rhetoric, linking high-profile figures within Labour to sensitive national security concerns. Whether these claims will prompt formal investigations, parliamentary scrutiny, or further political fallout remains uncertain, but they are expected to keep China, espionage, and diplomatic accountability at the forefront of UK political debate.
