Amir Khan is convinced the awarding of the 2012 Olympic Games to London can inspire an unprecedented family double.

Khan - who claimed a silver medal in Athens last year - kicks off his professional career in Bolton on Saturday night against David Bailey.

In seven years' time he hopes to be a long-standing world champion - and sitting ringside watching his younger brother Haroon go for gold.

Khan, who acted as an official ambassador for the bid, said: "Hopefully in 2012 I will be a world champion and Haroon can become an Olympic gold medallist at the same time.

"I am sure it will inspire kids to get involved in sport with the aim of taking part in the London Olympics.

"I was the only British boxer in Athens last year and that was not good enough but I am sure there will be many more by then because of the extra competition the 2012 Games will generate."

Haroon, 14, is already causing a stir in the amateur ranks after claiming a Four Nations Schoolboy title last year, and making the semi-finals of this year's Golden Gloves where he suffered a controversial defeat.

Haroon will miss the Beijing Games in 2008 due to age restrictions but father Shah believes he will be at his peak in time for London - and has the potential to be even better than his elder brother.

Shah said: "Haroon now has this great inspiration to work and train harder in order to try and make it for the London 2012 team.

"He goes through the motions sometimes but I am sure this will give him the extra boost he needs.

"I think Haroon is a lot sharper and stronger than Amir was when he was 14. So if he applies himself there is no reason why he cannot bring a gold medal back."

In the meantime, Amir's aim to keep his side of the family bargain is expected to begin in front of a 6,000-strong sell-out crowd at the Bolton Arena.

Khan's four-round fight with Bailey, which will be televised live on ITV1, is nominally on the undercard of Matt Skelton's British heavyweight title defence against Danny Williams.

But the fact Khan's fight follows the main event in the plum 10.30pm time slot leaves little doubt about where the loyalties of either ITV of the vast majority of fans in the arena lie.

Khan maintains he has had few problems settling into his new professional regime under trainer Oliver Harrison in Salford.

Khan added: "I'm training for longer hours and without a vest or headguard but it's been very easy to adapt and let it all flow.

"It's great to be with the pro lads in the gym because they've all been through what I'm going through now, and they're helping me keep my feet on the ground."
