I was referring to civil servants indeed but I do believe that the same thing applies to elected representatives. Without trying to undermine in any way the amalgamation of virtues and qualities (honesty, integrity, reliability, responsibility, kindness to name a few) which undoubtedly any MP should be an embodiment of, I still believe that MPs with degrees in politics / public policy are better able to adequately address and respond to the needs / problems of their constituencies. Having completed bachelor and / or master programmes in relevant subjects, these people obviously boast deep and well-grounded understanding of policy frameworks, policy evaluation, theories, policy stages and cycles, etc. That said they are well aware of the challenges ahead and the constraints, within which they have to operate while pursuing any policy objective.
