THE dad of Martine Vik Magnussen says a billionaire admitting he killed his daughter in a "sex game gone wrong" is a "gamechanger".
Farouk Abdulhak, 35, fled to Yemen in 2008 in his dad's private jet, hours after allegedly raping and murdering the Norwegian student in his Mayfair flat.
Martine, 23, had been on a night with pals celebrating coming top of her class before her strangled body was discovered in rubble in the basement of Abdulhak's Great Portland street address.
A post-mortem examination gave her cause of death as compression to the neck.
Since her murder, Abdulhak has refused to return to face trial in the UK.

But on Tuesday, the alleged killer admitted to his role in her death, telling the BBC: "I did something when I was younger. It was a mistake."
Speaking to MailOnline following the admission, Martine's father, Odd Petter Magnussen, said: "It's a gamechanger. He's no longer a suspect, he's now a killer.
"The fact that he's admitting his involvement means he is, by definition, a murderer."
He says the fess-up from Abdulhak could now change Yemen's long-held reluctance to deal with the case over fear of the power of his family.
The alleged killer is the son of late Yemeni billionaire Shaher Abdulhak who amassed a £6.8 billion soft drinks and petrol fortune, he died in 2020.
Because there is no extradition treaty between the UK and Yemen, it is difficult to force the alleged killer to return.
But Mr Magnussen said how he had been in contact with Yemeni officials and feels confident he could get Abdulhak extradited to the UK within a year.
Abdulhak's admission came as he was tracked down by BBC journalist Nawal Al-Maghafi who exchanged messages and a phone call with the alleged killer.
In their conversation he told Ms Al-Maghafi "I don't now what happened, it's all a blur" and how "if I smell certain female perfume I feel uncomfortable".

But he added Martine's death was: "Just a sex accident gone wrong.
"No one knows because I could barely piece together what happened."
Chilling CCTV showed Martine leaving Mayfair's exclusive nightclub Maddox at 2am on March 14, 2008, with Abdulhak, nicknamed 'DP' for his love of Dom Perignon champagne.
She had previously dated her alleged killer, a fellow student at the £10,000 a year Regent's Business School.
When Ms Al-Maghafi asked Abdulhak if he had any regrets, he said: "I deeply regret the unfortunate accident that happened."
Abdulhak later told her he would not be going back to the UK because they would "make an example of me being the son of an Arab" despite admitting he regretted fleeing.
He also grimly joked: "I don't like the weather there."
Mr Magnussen previously told the billionaire heir "you cannot hide forever" as he demanded he return to the UK to face justice.
He will the BBC in tonight's show: "He tried to portray it as a mutual accidental outcome of a sex act.
"It was definitely a sex act, but it was forced on Martine - as I can understand through the information I've gathered over the years."
When asked if he would speak to Mr Magnussen, Abdulhak said: "It would be too hard for me.
"It's been 14 years. What's another year or two. I don't really care. I don't want to talk about this. Move on please. It's making me feel uncomfortable."
The admission will be aired on BBC Two's Murder in Mayfair at 9pm on March 28.
