72 people died in the Grenfell Tower fire two years ago this week. Since then the first part of a public inquiry has taken place looking at the events of that night. The next phase, which will investigate why the 24-storey tower was wrapped in combustible cladding, will start next year. Kate Lamble from the BBC Grenfell Inquiry podcast tells what we have learnt so far. We also speak to Gill Kernick, who used to live in Grenfell Tower and works in risk management. She tells us what should be done to avoid this kind of disaster again.
