Tony and Tina Leigh plan to take their fight to Downing Street

Jessica Leigh, 14, died when she was knocked down in Bridge Street in Dover, Kent, in September 2003.

The 20-year-old driver was convicted of careless driving and was fined �300, ordered to pay �700 costs and given six penalty points.

Tony and Tina Leigh have launched a petition calling for changes and plan to take their fight to Downing Street.

We have got the life sentence Tony Leigh

So far they have collected 3,000 signatures in the past three weeks.

Mr Leigh said: "What we are trying to so is to get the law changed for people who kill.

"A car is a lethal weapon, and to me if someone drives it wrong and kills by it, whether it was an accident or not, he or she should get a stiffer penalty than what is pulled out now.

"Six points and a �300 fine for her death just amazes me.

"We have got the life sentence."

His wife Tina said: "Jessica was a fun loving beautiful daughter who was loved by everybody.

"He (the driver) has just put us through so much."
