well,I do not know from where did you find that I want the opposition into power.Infact as the left front has majority,removing BUdhdha would not change the Govt.I think you have not read my comments properly. To answer your points. To me,Anil Biswas could have been the perfect replacement.As he is not there one person who has a clean image is Khiti Goswami.The party can think of him.Or else they can also think of Gautam Deb.To answer your second point,there are people in the oposition who has intentions to do "Secret Trade" but there are quite a number of people like tathagata Roy,Rahul Sinha etc who would not be hungry to do Trading.
I would request you to read the comment first before properly before concluding anyhting from it.
