Pushed additional on whether or not he had knowledge or studies to again up the assertion, he added: “I’d say no I don’t suppose so and many of the evaluation had been primarily based on public data that was revealed daily.”

The PE panels got here in two variants – cassette and rivet – however the variations between their fireplace efficiency was “very nice” and the cassette type carried out “spectacularly worse” in a fireplace take a look at in 2004, the inquiry heard final week.

The e-mail went on: “This opinion is technical and anti-commercial it appears”, adopted by a smiley face.

Mr Wehrle is refusing to provide oral proof to the inquiry, citing a little-used French statute.

Coming to the top of his proof, Mr Schmidt was additionally given the chance to mirror on his function and admitted he didn’t “sufficiently nicely grasp technical assist in the middle of gross sales”.

He described it as “a criticism that I make of myself”, and added: “Most likely gross sales technical assist ought to have been in two elements, two sections.

“And the half which actually related to fireplace checks et cetera I believe it ought to actually have been positioned inside technical companies as a way to be sure that the duties had been extra clearly attributed.”

Mr Schmidt concluded: “I imagine that I merely didn’t have the presence of thoughts to understand that this service was primarily based on two very completely different axis and so they may very well be separated.”

In 2019, the chair of the Grenfell Inquiry panel, Sir Martin Moore Bick, concluded that the “principal motive” the flames shot up the constructing at such pace was the flamable cladding with polyethylene cores which acted as a “supply of gas”.
