"I have resigned from the BJP as it has lost its ideology and been compromising with corruption. I resigned as an MP too," Sushant told reporters in Delhi after resigning.
He was suspended from the BJP's parliamentary board March 11, 2012, on the complaint of the state unit.
For quite some time, Sushant, the MP from Kangra, has been openly criticising state party leaders, including former chief minister Prem Kumar Dhumal.
He was also axed from the party's state executive council in May 2011 for demanding a narco-analysis test of Dhumal and his then cabinet ministers over corruption.
Sushant was a minister in the state BJP government in 1998.
