British prime minister Theresa May is to meet victims of the Grenfell Tower fire disaster in her 10 Downing Street office on Saturday, officials said.
"The first person who spoke was a survivor from the 19th floor and - not quite my caricature of the Prime Minister - but to see her welling up, the response in the meeting, and to see her holding the hand of a sobbing lady next to her in the meeting was quite shocking I think to most of us there".
He said he was hopeful the meeting, which lasted almost two hours and was attended by victims, residents, community leaders and volunteers, was the starting point for a process of lasting change.
He described the residents as "brilliant" in how they raised and explained their concerns to Mrs May.
"That's why I'm positive about it, because I think in the past local residents here have not always been listened to".
He said: "I thought the way they expressed themselves with a mixture of passion and reason was fantastic, and I hope it's the beginning of a process, not the end of a process, the beginning of a process of real listening between Government, RBKC (the Royal Borough of Kensington and Chelsea council), local residents, that will bring about lasting change".
May released a statement following the meeting in which she said support on the ground for families in the immediate aftermath of the blaze had not been good enough.
Dr Tomlin said the residents had gone from living normal lives before the tragedy to bringing their frustrations to the very top of Government.
He added: "I think the thing that most encouraged us was it felt like she was taking charge and she wasn't allowing others to do it she was now going to make sure this happened and she was going to be personally responsible".
While being interviewed by Sky News near the tower block in west London, Mrs Leadsom was repeatedly challenged by angry residents.
Dr Tomlin said he believed residents left the meeting feeling "reassured that they were listened to".
