The 3,000-piece Zabludowicz art collection in Chalk Farm, north London, belongs to Helsinki native Zabludowicz, 64, and his Newcastle-born wife Anita, 56, who was appointed an OBE in the 2015 new year honours for services to the arts. His Polish Holocaust survivor father Shlomo built up the family business around Israeli defence contractor Solta, later diversifying into property and hotels. In 2011 the family’s London-based company Tamares sold its British Israel Investments operation for $700m. Israeli police have reportedly investigated Zabludowicz's connections with Binyamin Netanyahu, the country’s prime minister.
