In the UK, which of these is not studied as part of a PPE degree course?

Philosophy, Politics and Economics (PPE) is an interdisciplinary undergraduate/post-graduate degree which combines study from three disciplines.

The first institution to offer degrees in PPE was the University of Oxford in the 1920s. This particular course has produced a significant number of notable graduates such as Aung San Suu Kyi, Burmese politician, State Counsellor of Myanmar, Nobel Peace Prize winner; Christopher Hitchens, the British–American author, polemicist, debater, and journalist; Harold Wilson, Edward Heath and David Cameron, former Prime Ministers of the United Kingdom. The course received fresh attention in 2017, when Nobel Peace Prize winner Malala Yousafzai won a place.

In the 1980s, the University of York went on to establish its own PPE degree based upon the Oxford model; King's College London, the University of Warwick, the University of Manchester, and other British universities later followed. According to the BBC, the Oxford PPE "dominate[s] public life" (in the UK). It is now offered at several other leading colleges and universities around the world.
