He said that political parties were failing in their duty if they do not bring in public domain lapses of one another. In an interview to Karan Thapar on TV channel CNN IBN, Verma said he felt "completely disgusted" with lack of morality of Indian politicians.
Verma was asked about what he thought of Congress leader Singh's statement that he had information about certain instances which were equivalent to corruption on the part of family members of BJP leaders, but would not reveal them.
"Well, that is a very disturbing statement. Whether true or false. It has serious ramifications for our democratic polity. If true, it reveals a conspiracy at the top against combating corruption about which people are talking all the time and it shows that political morality is at its lowest ebb," Verma said.
"I would say in either case, if it is untrue, it is unfair to the people who are named. If it is true, then it is a very serious matter and it is not a personal matter. It has got something to do with the nation as a whole and I am really very disturbed that, that should be the understanding at the top," he said referring to Singh's statement.
Verma said that law enforcement agencies should take note and try to get information from Singh which he claims to have.
"If true, it indicates something in the nature of a very serious criminal offence and it is the duty of the law enforcement agencies to ensure that the rule of law is maintained," he said.
On questions relating to allegations against Congress chief Sonia Gandhi's son-in-law Robert Vadra, Verma said that not only the person in seat of power but also those in close proximity should also be above suspicion because they could influence decisions.
Verma was asked about the BJP's "reluctance" over asking questions about Vadra's land deals.
