Newspaper headlines: 'King's relief' Harry will attend coronation

The confirmation that the Duke of Sussex will attend King Charles III's coronation next month is the focus of many of today's front pages. The Daily Mirror sums up the situation with the headline: "Spare will be there".

The Daily Telegraph says the Duke is understood to have agonised over the decision for weeks, following the recent rift in the family. The Sun claims the King is happy that his younger son is coming back to the UK for the ceremony, but has "some disappointment" that the Duchess of Sussex and the couple's children will not be making the trip.

Some of the papers note that the Duke is expected to have a limited role - the Daily Mail's headline is: "Harry's blink and you miss it Coronation visit".

The Times says Whitehall officials and intelligence agencies are braced for the potential release of further information about sensitive military operations, following US intelligence leaks. The documents, which first circulated online, include allegations about the presence of British special forces in Ukraine. The Ministry of Defence says the leaked files contain a "serious level of inaccuracy".

A security source is quoted in the paper as saying it is worrying that there could be more revelations. The Daily Mail focuses on comments from a 20-year-old British student who discovered that the US intelligence leaks were posted online.

Some of the papers pick up on a report which says the UK is experiencing a "rapidly escalating" diabetes crisis. The charity Diabetes UK, which published the findings, says 4.3 million people have been diagnosed with the condition, and almost a million others are living with it, but have not yet been formally diagnosed.

The Daily Express has spoken to one family GP who says he has noticed the increasing number of people being diagnosed with Type 2 diabetes over his 40-year career, which has led him to conclude that "surely the time has come to invest in prevention".

The Guardian reports that more measures are having to be introduced so that music festivals in the UK can adapt to extreme weather conditions. The paper highlights the case of Standon Calling, a festival in Hertfordshire, which in the summer of 2021 was preparing for a dry weekend, then had to deal with a downpour which flooded part of the site.

A year later, after taking precautions following the flooding, the organisers had to deal with a heatwave. John Rostron, from the Association of Independent Festivals, is quoted as saying the biggest challenge for those he represents is a "lack of action on the climate".

Both the Mail and the Express have published photographs of Arnold Schwarzenegger fixing a huge pothole near his home. The actor and former governor of California posted footage of himself shovelling tarmac and explaining that he felt compelled to do something, as people in the neighbourhood kept complaining about the state of the road. Both papers have dubbed him the "Tar-minator".
