After the exit of Pawan Kumar Bansal and Ashwani Kumar,the opposition BJP has mounted pressure on the government by demanding the resignation of Manmohan Singh,saying the Prime Ministers position has now become untenable. The PMs position has become all the more untenable. Why they were sought to be defended for so long and why even Parliament was adjourned early,the reason is now clear, senior BJP leader Ravi Shankar Prasad told The Indian Express. PMs support to Ashwani Kumar was reflective of his own vulnerability. It was clear that the core of the status report was changed to save the PM. These resignations add more force to our demand for the PMs resignation. The Left parties said the resignations were not going to be enough for the Congress. These two ministers should have resigned at least a week back. The Parliament session was stalled unnecessarily because of this. Why the PM and Congress delayed this no one can understand, said CPM general secretary Prakash Karat,adding that his partys politburo and central committee would discuss these developments. Finally,good sense has prevailed in Congress. It should have come earlier. When the entire opposition was demanding Bansals resignation,both government and Congress adopted an adamant attitude which led to the House adjourning sine die ahead of schedule, CPI national secretary D Raja said here. The Trinamool Congress,which held the rail ministry for three years before the Congress took over in late 2012,said that time has come for cleansing of the system. It is a black day for India and Railways. The Railways Minister should not be allowed to have a say in postings and transfers anymore, said Trinamool MP and former Railways Minister Dinesh Trivedi.
