[SystemSafety] More on Cladding

[Martyn Thomas]

Dame Judith Hackitt FREng has been asked to chair an inquiry into the
building regulations. This inquiry is in addition to the main Public
Inquiry into the Grenville fire.

Judith Hackitt is chair of the Engineering Employer's Federation. Until
last year she was chair of the Health and Safety Executive. I worked
with her and I trust her to come to reasonable conclusions and
recommendations.

The Terms of Reference of each inquiry have not yet been published.
