Lindford Christie has said answers relating to the Grenfell Tower tragedy have to come quickler.
30 people are confirmed to have died after the tower block of apartments caught fire in the early hours of Wednesday morning.
The volunteer efforts to assist the victims have been continuing apace, and there has been a backlash against some politicians visiting the site.
Sadiq Khan was subjected to heckling as he arrived at the tower, while Theresa May has been criticised for not speaking to any affected by the fire.
Christie, who has won gold medals at every major competition open to British athletes, spoke to Sam Delaney about why they might be reacting this way.
The former sprinter, who was raised in nearby Shepherd's Bush, said: "We need straight-talking people, those who will tell the community everything is being taken care of and they’re in control.
"At the moment, I think everyone’s been diplomatic. This is west London, we’re straight-talking, upfront people.
"I think some of the people want answers of course. It’ll take time, but it’s got to come quicker than it is.
"Otherwise who knows what will happen."
