Yadav said opposition leaders, including Digvijay Singh and Anand Sharma of the Congress, Sitaram Yechury of the CPI-M and Tariq Anwar of the NCP besides representatives of many other parties, will attend the meeting in Madhya Pradesh tomorrow.
The BJP-ruled state had recently witnessed violent protests in Mandsaur by a section of farmers, and opposition leaders hope to build a campaign against the saffron party in the state that has emerged as its bastion.
The state will face the assembly polls by the end of next year along with Chhattisgarh and Rajasthan, two other states ruled by the BJP.
"I will hold a similar campaign in Gujarat and Rajasthan. I will go to other states too," he told PTI.
The "save composite culture" meet was organised at the national level on August 17 in which Yadav had made clear his intentions to defy his party chief Nitish Kumar's move to ally with the BJP, claiming that the country's secularism and pluralism was under attack in the NDA government.
