Explaining how the new board will work, His Excellency Yasir Al-Rumayyan said: "Whilst we are newcomers to Newcastle, we are investing alongside people who have been committed to this Club and this city for many years.
"Amanda Staveley’s PCP Capital Partners is a key part of our investment group. Jamie Reuben and his family are already significant investors in the city of Newcastle."
And on PIF's role, the new United supremo added: "The role of my team at PIF is a bit different.
"Our job is to look at the bigger picture – so we will be working with the rest of the Board to set the overall strategy, monitor how that is progressing and determine the changes we need to make.
"You will hear from us less often, but I can assure you that we will always be actively engaged."
And in thanking the Toon Army, the chairman of Aramco said: "I want to thank you all for the support you have given to this Club. Without fans like you, there is no Newcastle United Football Club and we will never take your support for granted."
