Separation of concern between the legislature (parliament) and the executive (the president and the cabinet) cannot be maintained if there are links between the two – especially if both comprise the same individuals. Members of the legislature should not hold ministerial positions. I have failed to find any provisions in the Sri Lankan constitution that forbid such intermingling. It should not be allowed. The concept of Balance of Power which is central to modern democracy can only work if the powers of the legislature, executive and judiciary are set AGAINST each other. Both the legislature and judiciary should be able to question the actions of the executive. This cannot happen if the branches are friendly to each other.
