The Saudi PIF website itself quotes “under the chairmanship and guidance of HRH Prince Mohammed bin Salman bin Abdulaziz Al Saud.....”
whilst the PIF is a legally distinct entity of course there are links. The Saudi PIF has royalty as Chairman you are correct, and he is in fact the Crown Prince and 'de facto' leader of Saudi Arabia which is, let us not forget, an absolute monarchy. In addition the PIF entity was founded by the King of Saudi with royal family money and is widely referred to as the Sovereign state fund - of course there is a link between the Royal family and the fund. The PIF is government funded - who runs the Government- the royal family.
let us not forget it is widely reported, and not denied, that MBS personally asked Boris Johnson to intervene and he is Crown Prince and chairman of PIF so of course there is a link
following human rights condemnation and Amnesty Internationals strong objections what the FA/PL wanted assurances about was that there would be no direct running of NU by MBS or the royal family.
There is a simple but distinct difference that needs to be understood between the funding of the acquisition, which is clearly made by the sovereign state fund of Saudi Arabia chaired by the absolute ruler of Saudi, and the assurances required that following acquisition members of the immediate Saudi royal family would not personally become directors of or personally involved in the day to day running of NU.
Confirmation was sought that there would be autonomy between PIF appointed directors of NU and the Saudi Royals. Whilst he has not been found guilty of any involvement in Khashoggi the evidence is widely acknowledged as overwhelming and compelling. MBS is not, as Colston suggests, 'proven ' guilty but the vast majority clearly feel he was heavily involved and the FA rightly wanted assurances that he would not personally be directly involved as a director of NU despite being chairman of the PIF
three entities were involved - the Kingdom of SA the PIF and NU ...What the Premier League wanted, and it was the PL that refused to ratify the deal not the FA and Ashcroft fought the PL in court, was a legally binding assurance that the Kingdom of Saudi Arabia would not control Newcastle United Football Club. There is a link between the PIF and SA and a link between PI and NU but there must be no link between SA and NU
that condition was satisfied so the takeover was allowed
