Astana: Prosecutors in Kazakhstan have charged the estranged former son-in-law of the Central Asian nation's president in absentia for the murder of two bankers.

A Kazakh court in 2008 sentenced Rakhat Aliyev to 40 years in jail on charges including attempting to overthrow the government.

Aliyev has managed to defy demands for his deportation from Austria by arguing that he would be denied a fair trial in his home country.

 General Prosecutor Askhat Daulbayev said on Thursday that Aliyev will now face a new trial. He has already been convicted on charges of kidnapping the two bankers, who authorities say were abducted in early 2007 after becoming embroiled in a commercial dispute with Aliyev.
