country's advances and Landon became a leading advocate of "Omanisation" of the economy and government. Later projects By 1979, Landon's position as an adviser had become a figurehead role. He returned to England, taking up a diplomatic post at the Omani embassy in London and establishing a home at Faccombe, a village near Andover in Hampshire. The title the "White Sultan" was regarded with bemusement by Landon, who maintained that Sultan Qaboos was very much in charge of Oman's destiny, and he was simply a servant and friend there to give advice. He continued to shuttle between London and Muscat until he died, his Boeing often seen arriving at or leaving Farnborough, the nearest airport to his home. Financial interests, philanthropy, and controversy Landon invested the money he had made during his time in Oman, diversifying his wealth into mineral exploration and farming in Africa, property and real estate investments in Europe and America, and a wide range of financial portfolios in global markets. His fortune was estimated at US$750 million or higher. Landon was known to be a patron of the arts and society as well as an avid conservationist, generously assisting with fundraising for foundations and charities. Landon also played an important role as intermediary in several questionable deals like when giant telecom company Ericsson sold telecommunications equipment to Oman in the late 1990s. The connection was revealed by a joint investigation into Landon's business by the Swedish Public Television "Uppdrag granskning" and Swedish Public Radio's "Dagens Eko" in January 2007. Landon was also behind another questionable deal when in 1999 Swedish jetfighter Saab and UK defence giant BAE Systems offered millions of dollars in bribes to Czech politicians to buy the Gripen jet-fighter. The real beneficiary of the money paid out was the Austrian Count Alfons von Mensdorff-Pouilly, a longtime agent for BAE and a first cousin of Landon's wife Princess Katalina Esterházy de Galántha. Mensdorff-Pouilly received secret commission contract of at least 81 million Swedish crowns for the final deal in 2003 when the Czech Republic leased Gripen jetfighter. Both the Ericsson Oman deal and the SAAB/BAE deal has been the focus of several police and parliamentary investigations. By 2008 investigations had opened in the Czech Republic, Hungary, Sweden, Great Britain, United States, Switzerland, and Austria. Tim Landon was also involved in the smuggling of a Bofors cannon to the sultanate of Oman in the 1980s.
