In his annual speech on threats to the nation, Sir Ken McCallum, the head of the UK’s intelligence service, MI5, warned that AI had the potential to ‘change the stakes’ on existing and even new bioweapons. To find out why, and how, Ian Sample speaks to Dr Tom Inglesby, director of the Johns Hopkins Center for Health Security and the Bloomberg School of Public Health. He explains what has governments so worried and what measures could be put in place to reduce the risks

The bestselling author says her books will no longer be supplied to UK bookshops over fears of prosecution. Zoe Williams and Haroon Siddique report

For now there might be a copy or two of Intermezzo left kicking around in your local bookshop – snap it up if you haven’t already, because soon that will be it.

Last year, Sally Rooney said she would be using her royalties to support Palestine Action, a group that is proscribed as a terrorist organisation under UK law. Since then, thousands of people have been arrested for supporting the group. Now, faced with the risk of prosecution under terrorism legislation, Rooney and her publishers have decided to stop supplying her books to retailers in the UK.

UK home secretary’s meeting comes after PM said he wanted to rejoin European law enforcement databases

The UK home secretary, Shabana Mahmood, will meet the EU’s home affairs commissioner on Monday for further talks just days after Andy Burnham said he wanted to rejoin European law enforcement databases from which the UK has been locked out of since Brexit.

Annual update from MI5 chief highlighted a complex cocktail that could have real-life consequences for Britain

MI5’s annual threat update covers so much ground it is easy to feel anxious. The terror threat has become more diverse, with far-right anti-migrant threats on the rise; while Iran has now firmly emerged alongside Russia as a country seeking to undertake violent and deadly plots in the UK.

“There is no law of physics dictating that rising state threats will be accompanied by diminishing terrorist threats,” MI5’s director general, Ken McCallum, said, although one of his core messages was that people and the country at large needed to focus on being more resilient. “In this new world, we should expect to be tested.”

Ken McCallum says Kremlin attempted to influence vote through social media and TV reports but had little impact

Russia did try to interfere in the Brexit referendum through social media and television reports, the head of MI5 said on Tuesday, but he added that did not mean the Kremlin had any impact on the result.

Ken McCallum endorsed comments by Andy Burnham, who raised the issue over the past two days, though he said continuing to debate it risked giving the Kremlin a needless propaganda victory.

Prime minister has reopened the debate over whether Russia sought to influence the 2016 referendum

Andy Burnham unexpectedly reopened an old Brexit debate when he said he had been told after becoming prime minister that Russia had interfered in the 2016 EU referendum.
