The conviction of Jimmy Lai in Hong Kong is another hostile act. How can Britain ignore Beijing’s provocations and human rights abuses?

The UK pushed hard to secure the release of Jimmy Lai, the newspaper publisher and British citizen who was a leading light in Hong Kong’s brutally suppressed pro-democracy movement. So, too, did press freedom and human rights campaigners. But the Beijing-appointed high court judges in the former colony convicted him anyway, finding Lai guilty last week on fake charges of trying to “destabilise” the Chinese Communist party (CCP). For Xi Jinping, China’s dictator-emperor, there is no greater crime.

Protesting to China’s ambassador, the UK’s foreign secretary, Yvette Cooper, condemned the trial as “politically motivated”. She’s right, of course – but her angry words will make no difference. Beijing’s contempt for Britain’s views is as painfully obvious as the UK’s weakness and indecision in the face of Chinese hubris. The breaking of its solemn promise to respect Hong Kong’s freedoms after the 1997 handover typifies the arrogance and untrustworthiness of Xi’s CCP.

The Golden State’s clean energy use hit new highs in 2025. As the Trump administration abandons US climate initiatives, can California fill the void?

As officials from around the world met in Brazil for the Cop30 climate summit last month, the US president was nowhere to be found, nor were any members of his cabinet. Instead, the most prominent American voice in Belém was that of the California governor, Gavin Newsom.

During the five days he spent in Brazil, Newsom described Donald Trump as an “invasive species” and condemned his rollback of policies aimed at reducing emissions and expanding renewable energy. Newsom, long considered a presidential hopeful, argued that, as the US retreated, California would step up in its place as a “stable, reliable” climate leader and partner.
