The mammoth presence of people in the rally yesterday established beyond any doubt that the party was united and strong in the state as never before, he said.
The senior Congress leader also thanked and congratulated the party leaders and workers for the "great show" of strength.
Singh today said in a message to the party workers, "I am touched, overwhelmed and indebted by the love, affection and honour you have bestowed on me by coming from different and distant parts of Punjab, braving fog and cold together, to make the Congress rally a monumental success in this historic town of Amritsar."
The rally had unnerved all the opponents like Akali-BJP who have already seen the writing on the wall that their days are numbered, he said.
"Let them have no doubts about that this was our declaration of final battle against you to ensure that you are out of Punjab sooner than later", he said, adding, "let me also add that their time is up and they can no longer continue to befool people of Punjab anymore".
