Thomas Sowell's book, The Vision of the Anointed also, albeit from an explicitly right wing American point of view, evaluates the political effect of the clannishness of "liberal" politics- with the subsequent advent of American neo-conservatism, it seems appropriate to apply his strictures across the political spectrum.
I will write further on this, but watching Peter Oborne was a breath of fresh air.
Constitutional reform is an urgent issue, not a theoretical one.
