In the early hours of the 14th of June 2017, a fire broke out in a tower block in West London. This fire was both a personal tragedy and a national scandal. It began in Flat 16 of Grenfell Tower. Before long, the flames reached combustible cladding and insulation, which had been installed on the outside of the building. Less than twenty minutes later, the fire had climbed 19 storeys to the top of the tower, ripping through the flammable materials. The tower was engulfed in flames at a staggering speed. Seventy two people lost their lives, hundreds lost their homes. For the past six years, a public inquiry has been hearing evidence about what lies behind the worst residential fire in UK peacetime in one of the richest areas of the country. Kate Lamble has reported on it since the beginning. And in this series, she tries to understand what created the conditions for a fire which was both foreseeable and preventable. The answer takes us to the heart of how Britain works, from the government and regulation, to business. This is a story of corporate deceit, government deregulation and a construction industry engaged in a race to the bottom. It’s a story of missed opportunities, unheeded warnings and the failure of a state to protect its citizens.
