THESE days, smiling Zak looks like any other schoolboy.

However, last year the 11-year-old was given just months to live because of a chronic liver disease.

He was given the gift of life after receiving a liver transplant from a Hampshire boy who died of an asthma attack aged just nine.

Now the parents of brave Jamie Stubbs savour every second of a special five-minute film, knowing their son saved Zak's life.

Dad Colin, 44, said: "I felt a real mixture of emotions at first. It was difficult to watch. "Zak was wearing a cap just like the one Jamie used to wear and it reminded me of him."

The footage is to be shown in a one-hour BBC documentary about Jamie's short life called Jamie's Wish.

A television crew followed Jamie's parents for a year after Mr Stubbs and his wife Sharon, 36, agreed to take part to raise awareness about asthma and organ donation.

It was in May last year that their son, who attended Mansel Junior School in Millbrook, suffered the fatal asthma attack.

His parents, of Studland Road, Millbrook, fulfilled his wish to donate his organs and they helped to save the lives of four people.

His lungs went to a mother-of- two in London, his kidneys to a grandmother in Oxford and a single father in the south of England and his heart valve to a three-year-old in London.

Mrs Stubbs, a sales assistant, said she loves watching Zak because it reminds her of Jamie.

"It's nice to think that someone has benefited. When you see Zak running around playing football and making silly faces it's like still having a part of Jamie here."

Now the couple and their daughter Kerrie-Ann, 14, are going to buy Zak, who lives in Middlesborough, a remote control helicopter for Christmas - something they know Jamie would have liked.

The couple had contacted the anonymous recipient families via their transplant co-ordinator to find out whether they wanted to be filmed. Only Zak's parents wanted to take part.

Jamie's Wish will be shown on BBC1 on December 16 at 9pm.
