Could Grenfell residents' health be in danger?

Who knows what we've got in our bodies now?

Residents living near Grenfell Tower are demanding to be tested to see whether they have inhaled any toxic gases from the fire which killed at least 80 people.

After the horrific 9/11 attack in 2001, it's estimated that at least a thousand people have died, and 37,000 recognised as unwell, as a result of their exposure to debris spread from the World Trade Centre towers. As fears mount among residents and firefighters that something similar could happen to them, Mark Williams-Thomas has begun an exclusive investigation.

He joins us on the sofa with a VT of some of his most shocking findings.
