Firefighters who battled the Grenfell Tower inferno have recalled the hellish scenes they encountered as flames devoured the building last month.

Speaking in an upcoming ITV documentary, commanders from the London Fire Brigade described how every member of their rescue team was prepared to die that night.

The scale of the crisis escalated rapidly as the blaze whipped up the structure in a matter of minutes, trapping dozens inside.

Pat Goulbourne and Richard Welch were the senior officers at the scene that night and set out the chaos as a rescue operation became entwined with the battle against the blaze.
