A twitter account created by the rebel camp also claimed that veteran journalist Kuldip Nayar would be among those attending the meet.
The group has claimed that it has received responses from around 3,591 people for the April 14 meet.
It also said that social activist Medha Patkar, who had resigned from AAP as it was rocked by internal differences, is going to attend the meet.
The rebel camp claims to have garnered the support of 968 volunteers in Delhi, 661 from Uttar Pradesh, 329 from Bihar, 301 from Haryana and 200 from Maharashtra.
The build-up to the April 14 meet has witnessed a series of allegations and counter-allegations with the dissident camp accusing Arvind Kejriwal loyalists of trying to scuttle the event while the party has issued a veiled warning to those intending to participate in the 'Swaraj Samwad'.
