New Delhi, March 01 (ANI): Aam Aadmi Party (AAP) leader Anand Kumar on Sunday refuted the reports of a rift within the party, adding that what was widely being seen as an internal 'cold war' was merely a difference of opinion. He further said that the party is united against corruption. Earlier, senior AAP leader Admiral L Ramdas had written a letter to party Chief Arvind Kejriwal as well as party members Yogendra Yadav and Prashant Bhushan, expressing concern over the growing divide and trust within the party. Ramdas, in his letter, reportedly sought to draw the attention of the founding members to the importance of 'internal unity' and appealed for a quick resolution.
