Mr. Stalin is not the first leader to try and broker peace between the two parties.

Hours before the joint Opposition meeting on Monday, Dravida Munnetra Kazgham President M K Stalin met Delhi Chief Minister and Aam Aadmi Party convenor Arvind Kejriwal.

Mr. Kejriwal is expected to participate in the meeting for the first time

In the 20 minute-long meeting, it is learnt that Mr. Stalin pleaded for Opposition unity. According to sources, he asked Mr. Kejriwal to drop his adversarial stance towards Congress and to join hands with Opposition to construct an anti-BJP platform.

However, sources in the AAP said that Mr. Kejriwal could be in a minority. Senior leaders of his party Manish Sisodia and Gopal Rai are adamantly opposed to any hobnobbing with the Congress, who are their rivals both in Delhi and Punjab.

Congress has consistently tried to block AAP's participation in the Opposition front. In the last skirmish between the two, AAP refused to vote in favour of opposition candidate for the post of Rajya Sabha deputy Chairman, after Congress president Rahul Gandhi failed to call on Mr. Kejriwal seeking his support. AAP had had three votes in the RS.

Mr. Stalin is not the first leader to try and broker peace between the two parties.

At the recent Kisan Mukti Morcha rally, Mr. Kejriwal and Mr. Gandhi shared a stage for the first time. There too, Communist Party of India (Marxist) General Secretary Sitaram Yechury made the two leaders talk and assure each other of one-on-one dialogue to sort out the differences.
