NCP working president Praful Patel on Tuesday said there is "no rift in the party" after NCP national secretary Sachchidanand Singh challenged the election of Maharashtra Deputy CM Sunetra Pawar as party chief. "The letter written by Sachchidanand Singh carries no weight," Patel remarked. Notably, Singh issued a legal notice claiming that Pawar's election held on February 26 was unconstitutional.
