This week, civil servant Brian Martin completed his evidence after more than seven days. In his concluding evidence, he said that there were several occasions on which he believed he could have prevented the Grenfell Tower fire from happening. And – almost five years on – politicians appeared for the first time. Two former ministers with responsibility for fire safety, Brandon Lewis and Lord James Wharton gave evidence – following calls to ‘bear the brunt of the blame’ – to explain their decisions and policies.
