A campaign group has accused an 80-year-old MBE recipient of exposing thousands of British children to Chinese Communist Party propaganda through Chinese-language schools.
Sin Hung Ng chairs the UK Association for the Promotion of Chinese Education (APCE).
UK-China Transparency (UKCT) released a report on Thursday alleging his organisation ran events celebrating the CCP and programmes tied to China's United Front.
Some activities backing Beijing's stance on Hong Kong reportedly involved children.
The late Queen honoured Ng with an MBE in 2000 for his work with Chinese community schools dating back to the 1990s.
UKCT claims his educational programmes advance political goals aligned with the Chinese state.
The UKCT report states Ng has long-standing ties to groups linked to the CCP's United Front Work Department (UFWD).
This arm of the party works to build influence abroad.
MI5 has previously warned the UFWD was "seeking to covertly interfere in UK politics through establishing links with established and aspiring parliamentarians across the political spectrum" and to "cultivate relationships with influential figures".
APCE provides teacher training, educational materials and cultural exchanges to Chinese-language schools across Britain.
The organisation says it works with more than 100 schools and thousands of pupils.
However, UKCT argues some of its activities amount to political advocacy.
The report highlights a 2021 APCE event marking the CCP's centenary where children performed and created artwork celebrating the party.
According to a UFWD-supported news outlet, the event featured content praising Mao Zedong's leadership and claiming the CCP had eliminated poverty in China.
APCE also ran a young reporters programme called "Generation Z China Stars Young Reporters' Station" with UFWD-overseen bodies.
Children received lessons from Chinese state media staff and produced reports for a Chinese-language outlet.

A 2019 Newcastle rally supporting Beijing's position during Hong Kong's pro-democracy protests also allegedly included children.
APCE photographs showed young people marching alongside adults waving Chinese flags.
UKCT raised safeguarding concerns about these activities.
Schools and charities working with children must remain politically neutral and shield pupils from inappropriate political influence.
Sam Dunning, director of UKCT, said: "Many people will doubtless be disturbed to see British-Chinese children brought into activities intended to promote and praise the CCP, an authoritarian political organisation that has orchestrated extensive cyber attacks against the British government and British organisations and companies, including the Electoral Commission, NHS and others."
The report also noted Ng served as honorary president of the Promotion of China Reunification Society in the UK, which campaigns for Beijing's position on Taiwan.
