Putting up its second best performance after 1992, the Congress won 77 seats in the 117-member Assembly while the SAD-BJP alliance was relegated to third spot with 18 seats. The AAP-LIP grouping secured 22 seats.
After guiding the party to victory, 75-year-old Amarinder Singh was sworn-in as the state's 26th chief minister along with nine ministers, including Navjot Singh Sidhu and Manpreet Singh Badal.
The winning streak of the Congress continued during the Gurdaspur Lok Sabha bye-election and civic polls.
The Congress, which promised to end all kinds of mafia in the state, found itself in a tight spot when one of the cabinet ministers Rana Gurjit Singh faced allegations of impropriety in the multi-crore sand mining, forcing Amarinder Singh to set up a one-man commission to probe the charges.
