The former head of marketing at the firm which rebranded a flammable insulation product as safe for use on high rise buildings has said he signed off the product’s marketing strategy because he was “relying on other people to give information”, the Grenfell Inquiry has heard.

Paul Evans, who worked at insulation manufacturer Celotex between 2007 and 2018, told the inquiry: “There was no-one coming to me saying, ‘we shouldn’t be launching this’.”
