THE family of Vicky Hamilton, who went missing six years ago aged 15, last night welcomed plans to print her picture on milk cartons in an effort to trace her.

Hers could be the first Scottish face to appear on the cartons, in a scheme run by the National Missing Persons Bur-eau and Iceland supermarkets.

Last night, Mrs Christine Hamilton, wife of Vicky's father Michael, said the move would delight her husband and Vicky's sister Sharon.

She said: ''I think it is a fantastic idea and Michael and Sharon will feel the same. Anything that can be done to try and find news of Vicky is welcome.''

Cartons of milk in Iceland stores throughout the country will carry labels showing pictures and details of missing children and vulnerable adults.

The first missing person label was launched yesterday, carrying a picture of Patrick Warren, 12, who disappeared with friend David Spencer on Boxing Day. A spokeswoman for the National Missing Persons Bureau helpline said they had 75 calls with possible sightings of Patrick in the six hours since the milk went on sale.

The milk carton scheme has been adopted from America where pictures of missing children are posted on milk cartons by police forces.

In Britain it will not just be confined to children. It will cover all missing persons classed as ''vulnerable'' - including elderly or mentally-ill people.

Vicky Hamilton, of Redding, near Falkirk, was last seen in Bathgate, West Lothian, waiting for a bus home. Less than a year later, in 1993, her mother, Janette Hamilton, died suddenly at the age of 41.

Mr Michael Hamilton, 46, recently said: ''We all still live in hope, but it's been a very, very long time now.''
