As I have mentioned earlier that, most of political members of Bangladesh are selfish and they are always looking for the chance to do corruption. If there is no Article 70, then there will be a serious chaos between party members. Moreover, as a small country Bangladesh need political stability to economic development. Article 70 of Bangladesh Constitution ensures the political stability.
