It's been just over two years since a fire broke out in Grenfell tower, in west London, claiming the lives of 72 residents. 223 people survived, thanks to the work of the fire brigade and health care.

In this podcast we hear from Andrew Roe, assistant commissioner at London Fire Brigade, and Anu Mitra, consultant emergency physician at St Mary's hospital - they talk about the support which has been provided, and where more needs to be done to help frontline staff cope with the horrors of the job.
