Good morning. Before the newsletter, an update on the news that broke last night that King Charles has been diagnosed with cancer. Buckingham Palace says that Charles is already undergoing treatment; it did not specify the type of the disease, other than to say it's not prostate cancer. You can read Rajeev Syal's analysis of the impact of the news on how the king carries out his role, and Andrew Gregory's cancer explainer.

Today, we're covering online safety for children, starting with a grimly familiar feature of the age: a devastated parent, granted a platform they never wanted, and using it to demand greater guardrails on smartphones to protect others from the fate that befell their child. At the weekend, Brianna Ghey's mother Esther gave an interview to the BBC in which she called for social media apps to be banned on smartphones for under-16s. Esther Ghey said her daughter might have been saved if the searches being made by her eventual killers had been flagged to their parents.

Crime | Detectives hunting the Clapham chemical attack suspect Abdul Ezedi have said they believe he is either being harboured from capture or is dead, with no trace of him for days despite a massive manhunt. Police said that a 22-year-old man arrested early on Monday for assisting an offender had been released on bail.

Middle East | At least six US-backed Kurdish fighters have been killed in a drone strike on a US base in eastern Syria. The attack, the latest indicator of how conflict has spread across the Middle East since the beginning of the war in Gaza, was claimed by an Iranian-backed militia that on Friday was the target of US airstrikes.

Child sexual abuse | Survivors and campaigners have criticised the failure to introduce mandatory reporting for child sexual abuse in England more than 15 months after it was one of the key recommendations by a public inquiry. None of the recommendations of the seven-year independent inquiry into child sexual abuse (IICSA) has yet been implemented by the UK government.

Labour | Labour has much work to do to retain support among Muslim voters, a senior party figure has said, as a poll suggested the party had lost a portion of its Muslim voter base over its handling of the Israel-Gaza war. Only 60% of British Muslims who backed Labour in 2019 are willing to do so again at the next general election, the survey finds.

Restaurants | London restaurant the Ledbury has been awarded three stars in the Michelin Guide for Great Britain and Ireland, becoming the sixth in the capital to be given the accolade. London's Gymkhana and Birmingham's Opheem become the first two Indian restaurants in the UK to receive two stars, while Crieff's Glenturret Lalique has become the second two-star restaurant in Scotland.
