It is almost one year since a lone gunman opened fire on a beach in Tunisia, killing 38 tourists - 30 of them British.

The attack - claimed by the so-called Islamic State - was the greatest loss of British life in a terror attack since the London bombings in July 2005.

One of the survivors, Colin Bidwell from Surrey, wanted to return to the resort of Sousse.

The BBC took him back for what he calls a journey of healing. This is his story.
