Senior leader and anti-Narmada Dam activist Medha Patkar on Saturday said that she has quit the AAP following dissident leaders Yogendra Yadav and Prashant Bhushan's expulsion from the party's national executive in Delhi.Announcing her decision at a hurriedly convened press conference, Patkar expressed pain over the development and said: "Whatever happened in AAP meeting is inappropriate and I condemn it." Patkar said the violence and other happenings show disrespect to the party's senior leaders and did not augur well and so she has decided to quit.Patkar is reported to have been unhappy with Delhi Chief Minister Arvind Kejriwal's style of functioning.Besides Patkar, several groups and activists of the National Alliance of Peoples' Movements are expected to follow suit.On March 6, senior AAP leader Mayank Gandhi had unfurled the banner of revolt by revealing AAP internal meetings and later claimed he was being targeted.
