In July 2005, Gaydamak became sponsor of the
Hapoel Jerusalem basketball team. The following month he donated $400,000 to the
Israeli Arab Bnei Sakhnin football club. On the same day, Gaydamak announced the purchase of 55% of the ownership of
Beitar Jerusalem, and two days later he announced the acquisition of full ownership. Gaydamak is the patron of several Jewish charities and president of the Congress of Jewish Religious Communities and Organizations of Russia (KEROOR), Russia's oldest Jewish umbrella group. In January 2006, Portsmouth F.C. was sold to his son, Alexandre Gaydamak by
Milan Mandarić. Gaydamak later sold the club to
Ali al-Faraj in 2009. In the summer of 2008, Gaydamak said his son Alexandre was owner of
Portsmouth F.C., and it was confirmed by the
Premier League. In March 2006, he announced having bought the French newspaper
France Soir via his company
Moscow News. He had purchased the Russian
Moskovskie Novosti newspaper in 2004, fired some senior journalists, and changed the paper's mandate to a firmly pro-government one, appointing a pro-
Putin journalist as editor-in-chief. In June 2007, Gaydamak negotiated a deal to buy the non-
kosher supermarket chain
Tiv Taam. It was reported that he was planning to make the stores comply with Jewish religious practice: close them on
Shabbat and halt the sale of pork products. A few days later the deal fell through, resulting in a lawsuit. In July 2009, Gaydamak announced his decision to give up the ownership of Beitar Jerusalem in favor of
Itzik Kornfein and
Guma Aguiar. Kornfein would handle buying and selling players, while Aguair would engage in financing. ==Philanthropy==
