TOKYO -- Type "boris, cameron, oxford" into Google, and a sepia photo appears showing a group of young men wearing bow ties, dark suits and black shoes. It is a commemorative photo of University of Oxford students belonging to the Bullingdon Club.
As the search results show, Boris Johnson, the prime minister of the United Kingdom who took office on Wednesday, and David Cameron, the prime minister before Johnson's predecessor, Theresa May, were members of the club at the same time. Bullingdon is an exclusive all-male dining club that goes back some 240 years. It is only open to students of posh families with aristocratic pedigrees.
