The first meeting of the Congress Legislature Party (CLP) in Karnataka will be held at 5.30 pm on Sunday, according to All India Congress Committee in-charge of Karnataka Randeep Surjewala.
The meeting is likely to decide the name of the new chief minister.
Special arrangements have also been made in the remote areas of the state to take them to Bengaluru and observers have also been appointed to do this exercise, party sources said.
The Congress on Saturday made a stunning comeback in Karnataka ousting the Bharatiya Janata Party from its lone southern citadel with a comfortable majority in a morale booster win that will be key for reviving its electoral fortunes ahead of the 2024 Lok Sabha polls.
The Congress' decisive victory in the assembly elections after an aggressive pro-poor campaign spearheaded by mass leader and former chief minister Siddaramaiah and Karnataka Pradesh Congress Committee president D K Shivakumar also saw Karnataka continuing with a 38-year-old anti-incumbency trend.
The state has never voted an incumbent party to power since 1985.
Siddaramaiah, 75, and Shivakumar, the party's trouble shooter who won from Kanakapura by over one lakh votes and who turns 61 on Sunday, are both front runners for the chief minister's post.
