The BJP MP from Nawada expressed his concern and said: "Hindu population decline is worrying, a law is needed on population control for all religions."
He went on to add that if such a law was not in place then "like Pakistan we too will have to keep our daughters under the veil."
According to a report in The Indian Express, Singh is quoted saying: "Hindu ka do beta ho aur Musalmaan ko bhi do hi beta hone chahiye. Hamari abadi ghat rahi hai (Hindus should have two sons and Muslims also should have two sons. Our population is declining).
Speaking to ANI he also said: "Population control law should be made, all must have 1-2 children. Those who don't follow, their voting rights should be revoked," Singh said.
In the past Singh has courted controversy several times. In the run up to the 2014 Lok Sabha elections, Singh had said that those criticising Narendra Modi should be sent to Pakistan.
