The Aam Aadmi Party (AAP) has initiated proceedings to disqualify seven MPs who defected to the BJP, following an unexpected shift by Rajya Sabha member
Raghav Chadha. According to AAP leader
Sanjay Singh, the party is formally requesting action from the Rajya Sabha Chairman.
Singh stated, "Anti-defection law clearly states that any type of split or faction cannot happen in the Rajya Sabha and Lok Sabha. It does not carry any legal recognition, even if it's a two-thirds majority." This legal contention arises amid growing tensions as
Chadha exited, citing AAP's perceived corruption as his reason for departure. He stated, "I gave the AAP 15 years of my life. Now the party has stepped away from honest politics. I am moving away and going close to the people. Today, the AAP is corrupt and compromised. It is not the old party. I don't want to engage in the wrongdoings of AAP," highlighting his dissatisfaction with the current leadership.
In a pointed response,
Bhagwant Mann, Punjab's Chief Minister and senior AAP leader, made a social media post using Punjabi culinary metaphors to criticize defectors, asserting that while individual spices enhance a dish, they cannot create a dish alone. He referenced, "Ginger, garlic, cumin, fenugreek powder, red chili, black pepper, and coriander -- these 7 things together make the 'sabzi' taste great, but on their own, they can't become a 'sabzi.'"
This provoked backlash from the BJP, which labeled Mann’s comments as an "insult" to farmers.
Additionally, veteran activist
Anna Hazare criticized the AAP leadership for the defections, stating, "It is their (AAP leadership's) fault. Had that party followed the right way, they would not have left." Hazare acknowledged the personal political agency of the defectors, emphasizing, "In a democracy, every person has a view about where to stay and leave."
