PARIS (Sputnik) — Swiss prosecutors have been investigating Karimova, 45, on suspicion of money laundering since late 2013.
"In view of the impossibility of contacting my trustee, I am deprived of the opportunity to defend her as required by a fair trial," Gregoire Mangeat said in a statement.
"In this regard, a new request for suspension of the trial has been sent to the Swiss Prosecutor General's Office," Mangeat added.
The Uzbek Prosecutor-General's Office said earlier on Friday that Karimova was is in custody following a 2015 conviction on a variety of corruption charges, and faces additional charges in a continuing investigation.
