British Foreign Secretary David Lammy has called for urgent answers from Hong Kong and Beijing after Wera Hobhouse, a UK opposition lawmaker, was denied entry into the Chinese-administered territory during a personal visit.

"It is deeply troubling that a sitting MP traveling privately has been refused entry without explanation," Lammy said in a statement on Sunday. "We are pressing Hong Kong and Chinese authorities for immediate clarification."

Hobhouse, a Liberal Democrat MP, shared her experience on social media, stating she is the first British parliamentarian to be turned away from Hong Kong since the city returned to Chinese control in 1997. “This was a cruel and distressing experience,” she said, noting that officials offered no reason for blocking her entry.

Speaking to The Sunday Times, Hobhouse revealed she had flown in on Thursday to see her newborn grandson and reunite with her son, who lives and works in the territory.

Her prior criticism of China’s Communist Party—including its suppression of freedoms in Hong Kong, alleged human rights violations in Xinjiang and Tibet, and aggressive posturing toward Taiwan and the South China Sea—may have played a role in the decision, though no official cause has been given.

Hong Kong's Security Bureau and immigration department, along with China’s embassy in London, have remained silent on the incident.

Hobhouse now joins a growing list of British lawmakers facing international travel bans. Just weeks ago, two Labour MPs were barred from entering Israel for a planned West Bank fact-finding mission, with Israeli officials citing concerns about potential incitement of anti-Israel sentiment.
