BJP's newly-appointed president Amit Shah will address a rally at Jind district on Saturday.
Shah, who will be addressing the rally in the afternoon today, is also expected to announce the induction of senior Congress leader Birender Singh into the BJP.
Congress is undergoing a crisis in Haryana two of its former ministers Chattar Pal and Harsh Kumar and ex-MLA Raj Kumar Balmiki joined the BJP at its Vijay Sankalp rally at Mahendergarh on Thursday.
Some prominent leaders of Indian National Lok Dal (INDL) Balbir Singh Saini, former minister and MLA and former MLAs Phool Singh Kheri, Banta Ram Balmiki and Krishan Kumar have also switched loyalty and joined BJP.
At the Vijay Sankalp rally, the new members were welcomed into the party by BJP leaders from the state including state unit chief Ram Bilash Sharma, senior leader and MLA Anil Vij, party's state affairs in-charge Jagdish Mukhi as well as Union Ministers KP Gujjar, VK Singh and Rao Inderjit Singh.
Speaking at the rally, Rao Inderjit Singh, who himself had joined the BJP recently after snapping his four-decade old association with the Congress, exuded confidence that BJP will form the government in Haryana.
"The BJP will form the government in Haryana," the Gurgaon MP said, asking people to oust the "corrupt and non-performing Congress".
Senior Congress leader and former state unit Chief, Phool Chand Mullana However said that those deserting the party at this time were "opportunists".
"If these leaders think that so called Modi wave is still blowing and they will gain something in BJP, then they are mistaken," he said.
Mullana also said, "People have realised that dreams were sold to them, but they will not fall in the BJP's trap again and will bring back Congress to power in Haryana once again on the basis of good governance and development works we have undertaken".
INLD MP Dushyant Chautala also asserted that the members leaving the party were "opportunists". He said this however would not affect the party's chances in the upcoming assembly elections.
Chautala claimed that the BJP was not finding candidates within the party and was therefore looking for other candidates who will contest the October polls.
