The physical wounds from that day are healing, but the psychological impact is impossible to measure. The survivors have chosen to speak as part of the healing process, in tribute to the little girls who didn't make it, to give voice to those affected and to make change.

It was the start of the summer holidays in Southport and a special event was organised. A Taylor Swift themed yoga and dance session for children run by two teachers. But a morning of fun turned to trauma. This is the first time that anybody who was in that room has spoken publicly.

A schoolgirl whose identity we've protected and is supported by her parents and the yoga teacher reveal what happened that day.

The teachers and their teenage helper knew they had to get everyone to safety.

Having been stabbed five times, Leanne moved more of the girls to safety. The other teacher, Heidi, saved a girl by sheltering with her in a toilet.

Three little girls would not survive. Seven-year-old Elsie Dot Stankham and six-year-old Bibi King both died on Hart Street. Nine-year-old Alice Aguirre was taken to hospital but died later that night.
