Truss or Sunak will the twelfth rather than thirteenth Oxford-educated Prime Minister since Baldwin – the others having been Attlee, Eden, Macmillan, Douglas-Home, Wilson, Heath, Thatcher, Blair, Cameron, May and Johnson.

After that, Cambridge will finally have its moment in the sun after the election of Kwasi Kwarteng or Suella Braverman in 2029.
