As such, invaluable insights into the processes of party evolution and change, and the implications of these changes, can be gained by examining broader research into the activities of political parties. In particular, highlighting the ‘party’ dimension within Green party research enhances the perception of the Greens as political actors who are integrated within the confines of competitive European party systems.
