I saw a survey once that identified the most right-wing and most left-wing universities based on political party preference
Top right-wing universities I recall are:
-Durham
-Exeter
-Imperial
-Warwick
-York
-Royal Agricultural College
-Hull
-Kings (pretty sure this is wrong)
Some Oxbridge colleges were said to be quite right-wing too, but not as entire universities
EDIT: To clarify, this survey was based off which party students would vote for. The ones I've listed are scored the highest proportion for conservative/UKIP voters. Definitely not representative of their SU!
