"The recent political crisis in Karnataka has badly exposed the BJP as a whole as the party has degenerated and no one is accountable to the party there," he said.
"Former Chief Minister B S Yeddyurappa himself selected his successor last year and then demanded his ouster even as the BJP's national leadership watched helplessly," Moily, who was here for a function, told reporters.
Yeddyurappa first selected Sadanand Gowda and later wanted himself to be reinstated as chief minister. He then wanted Gowda to quit and replaced by his another loyalist Jagadish Shettar. All these show BJP in a poor light, the former Karnataka CM said.
"Yeddyurappa's tenure was marred by corruption and caste politics. Karnataka, once politically stable and prosperous state, was now facing governance-related problems," he said.
Congress is strengthening its base in the southern state, where it hopes to do well in the next Assembly polls. In the last Assembly elections, BJP was short of majority but brought independents into its fold to shore up numbers, Moily said.
