This case remains alarming despite his release. The battle for press freedom must be vigorously pursued

Julian Assange should never have been charged with espionage by the US. The release of the WikiLeaks founder from custody in the UK is good news, and it is especially welcome to his family and supporters. He is due to plead guilty to a single charge of conspiring to obtain and disclose classified US national defence documents at a hearing early on Wednesday, but is not expected to face further jail time. The court in Saipan, a remote Pacific island which is a US territory, is expected to approve the deal, crediting him for the five years he has already spent on remand in prison.

His opportunity to live with his young family comes thanks to Australian diplomacy under the prime minister, Anthony Albanese, who had made clear his desire for a resolution, and the Biden administration’s keenness to get a controversial case off its plate, particularly in an election year. Seventeen of the charges have been dropped. The one that remains, however, is cause for serious alarm. It was the Trump administration that brought this case. But while the Biden administration has dropped 17 of the 18 charges, it insisted on a charge under the 1917 Espionage Act, rather than the one first brought against him of conspiracy to commit computer intrusion.

Seventy years after research linked cigarettes with cancer, tighter controls have been delayed once again

Seventy years ago, the British government recognised that smoking caused lung cancer, thanks to a breakthrough in medical science. In an interview to mark the anniversary, Sir Richard Peto, a pioneer in this area, highlighted one way in which the discovery was significant. It led, he said, to a boost for public health comparable with 19th-century improvements in sewerage and water quality.

The shift in attitudes to smoking did not happen suddenly. The tobacco and vapes bill championed by Rishi Sunak, which fell when he called an election, was the culmination of a decades-long process. If the law is resurrected by the next government – as seems likely given the inclusion of similar measures in Labour’s manifesto – it will become illegal to sell tobacco to anyone born since 2009, and vapes will be more tightly controlled.
