Panthers Party chief Bhim Singh shot off letters seeking support for Karan Singh to top leaders of all parties, including Congress chief Sonia Gandhi, BJP leader LK Advani and CPI(M) General Secretary Prakash Karat.
In his letters, he said Karan Singh is the "most potential" personality with international understanding and recognition who "shall prove a unique ambassador of India to dilute international tension."
He said Karan Singh deserves consideration and he is acceptable to all sections of society. In an apparent reference to PA Sangma's bid for Presidentship citing his tribal identity, Bhim Singh said the head of the state should not be identified with his colour, religion, region or caste.
He urged Left parties not to oppose Karan Singh because of his royal lineage. He said he has already spoken to regional party leaders like Mulayam Singh Yadav, Mamata Banerjee and Chandrababu Naidu.
The Panthers Party had during a three-day camp in Jammu and Kashmir's Udhampur passed a resolution supporting the candidature of Karan Singh. Panthers Party has four MLAs in Jammu and Kashmir Assembly.
