Emails that appear to show the architect, contractor, facade specialist and fire engineer working on the refurbishment of Grenfell Tower knew that the cladding would fail in the event of a fire have been published by the public inquiry.

They were contained in evidence submitted this morning by insulation manufacturer Celotex as it sought to argue that the designers, contractor and consultants involved in the refurbishment bore responsibility for the performance of the cladding system in the blaze.
