The Premier League has been urged to re-examine assurances given by Newcastle's Saudi owners that the Middle East state would not have control of the club following the filing of a new court document in the United States.
The document filed earlier this week has raised fresh questions about the level of separation between the Saudi state and the Public Investment Fund (PIF), whose governor Yasir Al Rumayyan is also chairman of Newcastle.
A brief filed in a court case involving the PGA Tour and LIV Golf describes the PIF as 'a sovereign instrumentality of the Kingdom of Saudi Arabia' and Al Rumayyan as 'a sitting minister of the Saudi government'.
