LONDON/NEW YORK, June 18 (Reuters) - Greylock Capital is stepping back from its 'steering committee' role on the Venezuela Creditor Committee but will remain a member of the wider group, two sources told Reuters on Thursday.

The move is likely to be seen as an early sign of strain within the group as it waits for Venezuela's financial advisors, Centerview Partners, to provide a key debt sustainability analysis report later this month ahead of what will be one of largest and potentially most complex debt restructurings ever undertaken.

The steering committee represents a core group of major creditors that coordinates negotiations with a government that is restructuring its debt, formulates restructuring proposals, and seeks to align broader creditor participation on agreed terms.

A legal representative for the VCC, which also includes the likes of GMO, Fidelity, T. Rowe Price, Mangart Capital and Morgan Stanley Investment Management, did not immediately respond to a request for comment.
