Oxford Analytica, the research firm, continues to collect stars for its advisory board. Its latest catch is Rudi Bogni, former chief executive of private banking at UBS. He takes the slot left vacant after Dick Cheney stepped down to become vice-president of the US. Bogni used Oxford's seriously informed analysis on world affairs while at UBS, and joins a former UBS Warburg colleague Jens Tholstrup, who is now a director of Oxford Analytica. Other advisers include Albert Scardino, the Pulitzer prize-winning husband of Marjorie, who runs Pearson. That is when he has time away from running his latest plaything, Nottingham County Football Club.
