Intra-party democracy
We, unfortunately, are lacking in both. Thus we see matrimonially horizontal or genetically vertical flow of anointed leadership in both major political organisations. An organisation that does not practice intra-mural democracy cannot be and ought not be expected to follow democratic principles especially when it is endowed (!) with the entire governmental prowess. The Awami League (AL) did it. The BNP just gave it an extra dimension.
No great improvement in the current political paradigm can be expected until the party-structure becomes more democratic allowing the leadership to grow up from the bottom and not imposed from the top.
