democratisation of representative elite

The paper reveals the process of institutionalisation of the Bulgarian Parliament for the period from 1991 to 2018, by examining three dimensions: /1/ the par- ty discipline and cohesion; /2/ the changing structure of parliamentary representatives; /3/ the legislative process. The paper reports the results of a longitudinal study of Bulgarian parliament aimed at identifying factors, drivers and stages of its institutionalisation and democratisation such as changes of rules and regulations, landslide electoral victory of new parties, presidential veto and judicial review.
