The grieving mother of a teenager killed by a speeding driver said she was dreading this year more than any other.

It has been nearly two years since Natasha Groves' daughter Lillian was taken from her at the hands of a driver who had smoked cannabis before his speeding car ploughed into the 14-year-old.

“I will find it harder than last year,” the 42-year-old said from family home in New Addington. “It is because of all the milestones.”

Lillian, who went to Addington High, would have turned 16 this year and would be leaving school to start college.

But there was one thing more than any other she was looking forward to - her school prom.

“She watched her sister do it and she said she could not wait,” her aunt Michaela explains.

“She was more than excited. She talked about it for years and years.”

Natasha confesses to using ageing computer programmes on Lillian’s photos to imagine what she might have looked like as an adult.

"You can’t help but look at the other girls [daughter Rhiannon and cousin Meg] and wonder how they look like her - how tall she would have been etc.

"We won’t see her get married or have children."

In the aftermath of the tragedy, the family launched a campaign to introduce Lillian’s Law, giving harsher sentences to drug-drivers and introducing roadside drug testing.

It has been gathering pace with the Prime Minister setting up an expert panel to discuss the new legisltation.

Michaela, who is disappointed someone affected by drug driving is not on the panel, said: “I am so frustrated because I don’t know when this first meeting is .

“You can have all the letters after your name but none of them have been through this.”

The family say they are no different to any other which has been affected by tragedy, and sometimes wonder why they are the ones who have taken on the challenge.

“Sometimes you do feel like you are the only one.”

But they know there could be hundreds of other families who could not know if drugs were a factor in the accident because of the lack of roadside testing.

Trying to change that situation, added to their grief of losing a loved one so young, gives them the determination to make a difference and they are more resolute than ever to succeed.

“We are not going to give up and we are passionate about it,” Natasha says, “We need to be on their backs.”

Michaela adds, “If that is why she was put here, to change the future for others affected, then what a legacy that is.”

Natasha, has the final word, “We can’t let her down.”
