I think you dont know any thing. It is the leftists who are withdrawing support from the UPA govt. It is not the job of opposition party to provide numbers to the govt. UPA has to prove its majority in parliament. Pls think before writing any thing. I think you have forgotten how congress withdrew support from Charan Singh, Chandra Shekhar, Deve Gowda and I.K.Gujral without any reason.What do you want from BJP. To vote for UPA in parliament.
