In a letter to the Legislative Council, Chairman Ramesh Yadav, Leader of the BSP Legislature Party in the Upper House Sunil Kumar Chittor informed that Siddiqui had joined another party on Feburary 18 after resigning from Mayawati's party on his own.
Hence, it amounted to violation of the anti-defection law, BSP national general secretary SC Misra said, quoting Chittor's letter to the Council chairman.
Siddiqui had become a BSP MLC on January 23, 2015 and quit the party to join the Congress on February 18.
In an application to the council chairman on June 29, the party had demanded that Siddiqui should not be given any facility or allowance that he used to enjoy as a legislator.

It was on May 27 that Siddiqui floated a new outfit, the Rashtriya Bahujan Morcha, after he was expelled from the BSP.
Siddiqui and four former UP ministers had last week formally joined the Congress.
