A grieving mum has made an emotional plea for tougher sentences for people convicted of causing death by dangerous driving.

Nicola Coleman lost her husband Valentino and her 21-year daughter Olivia when a van ploughed into their car, which had stopped due to a puncture on the A299 in Thanet.

The driver Sivananthan Mathivathanan was given a 10-month sentence, suspended for two years, and a three-year driving ban.

Speaking to KMTV, Mrs Coleman said: "Basically he [Mathivathanan] walked away that day and went back to his family.

"I feel that the sentencing for these awful tragic incidents that happen are not strong enough.

"We just don't feel we've got justice.

"We feel we've been let down so badly and we don't want other families to go through what we're going through right now."

The petition, which will run until the end of July, has already received backing from more than 1,900 people. It requires 10,000 for a government response, and 100,000 for the matter to be considered for debate in Parliament.
