NEW DELHI: "Pehle khana khate hain, phir kal ki tayyari karte hain (let's eat first and then prepare for tomorrow)," Prime Minister Narendra Modi greeted opposition leaders at a dinner hosted by Speaker Sumitra Mahajan , jocularly referring to a predictable government-opposition showdown when Parliament 's monsoon session begins on Wednesday.The interaction between the PM, opposition leaders and senior ministers is likely to be the only occasion marked by a relaxed informality as the monsoon session gets underway with a set of important assembly polls just a few months away. The heated political rhetoric, marked by polarising overtones, is already marking a slow descent into Lok Sabha polls due around March next year.Read also: Monsoon Session of Parliament 2018 live updatesThe Speaker's dinner has often seen the PM share his assessment of international events and his meetings with foreign leaders. He has earlier exchanged impressions on US President Donald Trump and discussions of the G20.A day before Parliament opens for the last monsoon session in this Lok Sabha, Congress announced that it would bring a no-confidence motion against the government and urged the Centre to accept it to enable a discussion.The opposition stance indicates that the standoff between the two sides which saw the budget session being almost washed out will in all likelihood continue.Congress leader in Lok Sabha Mallikarjun Kharge said the no-confidence issue was discussed with other opposition parties to forge a common stand. Telugu Desam Party (TDP) has submitted a notice for no-confidence in the House and will raise it on Wednesday.The opposition raised the demand again on Tuesday, by writing to the Speaker. Signed by Congress, CPM, Samajwadi Party, NCP, IUML, CPI, RJD and others, the letter alleged that BJP had denigrated rules and asked if Mahajan had written to the PM, asking him to stop such "subversion".At the all-party meeting called by the Speaker on Tuesday morning, BJP's partner Shiv Sena brought up the issue of "lynching deaths and fake news," saying Maharashtra saw five such killings recently while there was a BJP government at the Centre as well as in the state.At another meeting of leaders in Rajya Sabha, Chairman M Venkaiah Naidu urged MPs to ensure the monsoon session was different from the chaotic budget session. Leader of opposition Ghulam Nabi Azad said the government should begin with legislations with "wider acceptance".Read this story in Bengali
