This week, more than seven years after the Grenfell Tower took 72 lives and devastated many more, the inquiry into the disaster is due to publish its final report. It is likely to apportion blame to an extraordinarily wide range of parties – the manufacturers who knowingly sold dangerous cladding and insulation, the civil servants who turned blind eyes to mounting evidence that these materials could cause catastrophic fires, the contractors who carried out shoddy work, the rich local authority who refused to spend money making sure that fire safety precautions were up to standard.

They seemed to share a culture of contempt, for facts, due process and, above all, the people, many of them disadvantaged, who lived in the tower. Meanwhile, justice remains to be done – it might take another three years before any of the culprits appear in court. And thousands of homes continue to be endangered by the combustible materials used on Grenfell. It is hard to think of a more comprehensive failure of private and public bodies. One can only hope that the government response will be equal to the scale of the scandal.

There's more on Grenfell in today's Observer, along with stories, features and comment covering everything from Tony Blair and Elon Musk to cooking at home and fatherhood.

When he became UK prime minister in 1997 Tony Blair was in his early forties and an absolute neophyte at governing. He was much better at it, he believes, towards the end of his decade at No 10 than at the outset. So he's written a book about the dos and the don'ts of leadership "because government is a science as well as an art". Ahead of publication he talks to the Observer chief political commentator Andrew Rawnsley about relinquishing power, why he's not fazed about a second Trump term – and why he's an AI evangelist.

Caribou, AKA festival mainstay Dan Snaith, is back with a bang(er). Following 2020's slinky, introspective Suddenly, new single Come Find Me feels like the aural equivalent of placing your brain in a pool of cool water as the emotion washes over you in waves. Accompanied by a deliberately unsettling music video in which a mysterious figure dances around the London Overground wearing a mask cutout of Snaith's face, the track embodies many of the elements that make up Caribou's core appeal, combining his trademark pristine beats with deceptively simple yet poignant lyrics. It trails a new album, Honey (via City Slang, 4 Oct), a four-night residency at London's tiny The Waiting Room, N16 (8-11 Sept) and a UK tour next February. Listen to Come Find Me and much more on our best of 2024 Spotify playlist, updated weekly.

This seems to show the proverbial light at the end of the tunnel, almost exactly as experienced by those who speak of a near-death experience. A tiny angel rests on the edge of a brilliant disc of light. This is part of a four-panel polyptych featuring true and innocent souls as well as the damned. Laura Cumming
