Sulaiman Al Fahim is looking forward to leading Portsmouth into a successful era after being confirmed as the club's new chairman.
After a turbulent summer, Pompey were told by the Premier League on Tuesday morning that they had ratified Al Fahim's takeover of the club.
Al Fahim will join the existing four-member board at Fratton Park as chairman with immediate effect.
He said after his appointment was confirmed: "I very much look forward to working closely with the club's management and supporters to develop Portsmouth Football Club and deliver future success.
"The club has a long and fine history of achievement that I intend to build on."
Chief executive officer Peter Storrie added: "This appointment brings stability to the club and is excellent news for Pompey supporters.
"I have every reason to believe that, together with the new chairman, we will be able to take the club forward to further achievements, building on the successes of the past three years."
