Who cares about white or black or hawala? This matter should be probed with highest integrity to ensure that the guilty has to be punished to save some grace from this ugly incidence. The MPs have so many other options to make money, why do it this disgraceful way? Our country where there's corruption so widespread, it was naive to think that the parliament is untouched. The only issue here is that a very important topic for country and the future is decided this fashion.
