CST - City Congress president Sanjay Nirupam has termed the allegations of NCP spokesperson Nawab Malik as baseless in which the NCP leader had accused Nirupam of being a Shiv Sena supporter and obstructing an alliance with the Congress Party. Nirupam said that a decision not to tie up with the NCP was not mine but it was taken at the meeting attended by former MPs, MLAs and senior Congress leaders. The high command was also informed about this decision.
