SUPPORT for Hannah Leffler’s campaign for a change in the law on one-punch manslaughter sentences is growing.

A Facebook group set up by Hannah, the 18-year-old whose dad Martin died after being punched outside the Old Red Lion Pub by Michael David Slack in December 2008, now has more than 1,359 online supporters.

‘Justice for Martin Leffler and all other victims of one punch manslaughter’ has also gained support families of other victims.

All are keen to rectify the startling difference between minimum sentence for manslaughter – 12 months – and the 15-year minimum for murder.

Hannah is calling for people to show their support by signing a petition to Number 10 calling for tougher sentences online at

The petition was set up by Joanne Foster, whose boyfriend Neil McDonald was killed with one punch after enjoying a quiet drink with her in their native Macclesfield.

On January 22, John Anthony Cunningham, 30, was sentenced to nine years in prison at Chester Crown Court.

But he could be free as early as February 2012 because of time served.

Neil’s bereaved girlfriend Joanne Foster is organising a march in London to draw attention to their plight.

But Hannah may miss the event after receiving some good news in her ambition to become a paramedic and emulate the medical staff who helped her father as he fought for his life.

This week, she had an interview with John Moores University in Liverpool to study paramedic practice. Within five hours she was called back to say she was one of 20 successful applicants from 900.

She said: “She said they were really impressed. I’d always thought of being a paramedic but seeing how they helped dad really made me want to do it.”

Hannah must now complete a fitness test to assess her ability to perform as a paramedic which could clash with the march. Joanne Foster has told her that Martin’s face will be on a banner at the march even if she cannot be there in person.
