LONDON, April 9 - The five leading holders of Ukrainian sovereign and quasi-sovereign bonds have formed a creditors' committee to propose a solution to Kiev's debt problems, but resist plans for a writedown under an IMF-led bailout deal, Reuters reported.

The committee's creation was announced in a statement received by Reuters on Thursday from the Blackstone Group and law firm Weil, Gotshal and Mange, which are advising Ukraine's biggest creditor Franklin Templeton. The asset manager is estimated to hold over a third of Ukraine's outstanding sovereign debt.
