"Nobody knew that BJP, who had invited ISI to probe the Pathankot terror strike, was nurturing Pakistan agency agents in its own party," Delhi Labour Minister and party's Madhya Pradesh affairs in-charge Gopal Rai told reporters here.
"This fact came to light, when the ISI espionage racket (snooping important Indian establishments) was bared in MP. Efforts are on to cover-up the issue," he alleged.
"It is surprising that such persons have entered your house and your party and you are not aware of it," he said.
Rai said BJP after coming to power at the Centre has portrayed "nationalist hypocrisy".
"Its slogans about patriotism had raised doubts since the beginning given that its founders had no connection with nationalism during the freedom struggle," he added.
The ATS had arrested eleven people for allegedly being part of espionage ring from various places in Madhya Pradesh.
