The parents of murdered Harry Potter actor Robert Knox have called for a mandatory six month minimum custodial sentence for anyone caught carrying a knife.
Colin and Sally Knox were speaking in Downing Street following a meeting with Prime Minister Gordon Brown, Home Secretary Alan Johnson and other families of knife crime victims.
Robert, 18, was stabbed outside a bar in Sidcup, south-east London, in May last year.
Mr Knox said that carrying knives on the street was "abhorrent" and added he wanted the Government to change the law.
He said: "The Knox family felt it only right and fitting that the way they could fight knife crime in this country was to propose something to this present Government.
"We're actually calling for a mandatory six month minimum custodial sentence for those people caught and found guilty of carrying knives.
"Carrying knives is abhorrent and people shouldn't carry knives in this country. They're used as weapons to kill innocent people."
He said he had written to both the Prime Minister and the home secretary and said: "It's up to them to take that on board and give me a reply."
His wife added: "If you carry a knife you will use it. A lot of people who have died have never carried a knife in their life. If you carry a knife, you're going to kill."
The couple have set up organisation Families United for relatives who have lost loved ones. They include the parents of Jimmy Mizen and Damilola Taylor.
