More than a quarter of firefighters exposed to toxic smoke during the Grenfell Tower fire have had long-term health disorders, a study shows.

Ministers are facing demands for an urgent review after data from 524 firefighters who risked their lives at the 2017 disaster showed that over the first three years, 136 reported life-changing conditions. These included 11 cases of cancer, 64 respiratory diseases, 22 neurological disorders and 66 digestive illnesses.

Up to 2020, the rate of digestive and respiratory disease among the firefighters who were exposed to smoke during the fire was three times as high as among those who were not, the report found.

Due to be published on Friday, the report said that establishing a Grenfell firefighters’ health-screening programme similar to one established for those who served in New York after the 9/11 atrocities could cut the number of premature deaths.
