Martin Weaver was one of the specialists working with the bereaved, survivors and first responders following the 7/7 bombings.

He was part of a team providing psychological support, psychotherapy and counselling.

Martin has since set up a programme for dealing with traumas, like that of 7 July 2005.

In an interview with ITV News London, he describes his role on that day eight years ago - and how he's been working with survivors since.
