AAP's announcement welcoming support from every quarter has been a domino effect with political parties from the Left to the Trinamool Congress, taking up their call to arms and announcing their support for the Aam Aadmi Party.

The Delhi elections are being closely watched by political leaders across the spectrum, with many regional parties in particular, praying that AAP will break the stranglehold of the BJP in India. States like West Bengal and Bihar which will go to polls in the next two years, in particular are looking for a chink in the BJP armour, which has seemed impenetrable so far.

Little wonder then that these avowed 'secular' leaders are suddenly issuing calls, asking the people of Delhi to support AAP. Here is a list of leaders who are batting for AAP this election:

1. Mamata Banerjee

West Bengal Chief Minister and TMC president Mamata Banerjee on Thursday issued a statement saying, “My request to all of you in Delhi is to please vote for AAP… for the greater need of the country and development in Delhi.”

According to the Indian Express, Mamata's call for support to AAP is also in line with her policy for a “federal front” made up of regional parties.

However until now, Banerjee has opposed to Arvind Kejriwal and his party as she feels they have only copied her political funda— simplicity and a “common man” lifestyle.

2. Nitish Kumar

Former Bihar chief minister Nitish Kumar may shortly issue an appeal to people to back AAP candidates.

He has already wished Kejriwal the best of luck. The Bihar consortium of Janata Parivar has backed the AAP as well. The group’s constituents have fielded a total of only five candidates in order to not divide the anti-BJP votes. The JD(U) and the Samajwadi Party have also fielded two candidates each.

3. HD Deve Gowda and the Janata Dal (S)

Mamata Banerjee’s appeal to her followers to support AAP came a mere 24 hours after the Left parties and former Prime Minister H.D. Deve Gowda asked their activists and supporters to back the AAP wherever its candidates were not in the running. Nitish Kumar’s Janata Dal (United) had also made a similar request to his followers.

4. Prakash Karat and CPI(M)

The CPI(M) general secretary Prakash Karat has asked all party members and supporters to vote for the AAP in 55 seats in the Delhi assembly elections. The Left parties have suffered huge losses in the last two Lok Sabha elections and the West Bengal Assembly elections, and to solidify the anti-BJP votes they have come out in support of the AAP.

5. Mallikarjuna S. Khurbe

A Janata Dal (s) MLA Mallikarjuna S. Khurbe, from Karnataka’s Basavakalyana Assembly constituency, was waiting to present a cheque for Rs 1,08,000 to Kejriwal on Thursday, reports the Hindu.
