Leaders from Opposition parties have been mounting pressure on the Central government to hold discussion on the issue of Parliament security breach as both the Houses are set to meet on Monday during the ongoing Winter session. 


On December 13, when the country was observing 22 years of terror attack on the Parliament, two men broke into the Lok Sabha chamber from the public library during Zero Hour and released yellow smoke from canisters and shouted slogans, before being overpowered by the MPs.


Around the same time, two others released coloured smoke from cannisters as they shouted "tanashahi nahi chalegi" outside the Parliament premises.


Ahead of Parliamentary proceedings on Monday, Congress MP and Leader of Opposition in Lok Sabha, Adhir Ranjan Chowdhury said: “The Opposition wants to talk about the breach in the security of the Parliament, the pass given by BJP MP and loopholes in the security...This is a very serious issue for us."


Targeting the Bharatiya Janata Party-led Centre over the issue, Shiv Sena (Uddhav Balasaheb Thackeray) MP Sanjay Raut said, “If there was any other party in power at the Centre, then BJP would have shut down the entire Delhi on this issue.”


“No action was taken against the BJP MP who gave these people (accused in incident) to enter Parliament...There should be no politics on this issue of national security. He (PM) should speak on this issue in Parliament,” he added. 


The BJP has accused the Opposition of politicising the issue to which Congress MP KC Venugopal said, "The PM says this is a serious issue but he is not ready to discuss it in the Parliament." 


"We have only one demand- we need clarification from the government. But the government is not giving any clarification. Then who is politicising the issue," he added. 


The Delhi Police has arrested six people in connection with the security breach matter namely Sagar Sharma, Manoranjan D, Amol Shinde, Neelam Devi, Lalit Jha and Mahesh Kumawat.
