Online shoppers will have to collect knives in person rather than having them delivered to their homes under Government proposals to clamp down on sales to children and teenagers.

It is already an offence to sell knives to under-18s but the planned measures would mean they cannot be delivered to private property, such as the buyer's home.

Ministers say this would make it harder for under-age purchases to go undetected following warnings online age verification checks can be sidestepped.

Under the plans anyone who bought a knife on the internet would be required to collect it at a store or another physical premises.
