The BJP has demanded that the centre come out with a 'white paper' on the issue of non-governmental orgaganisations getting foreign funds and "working against public interest."

Prime Minister Manmohan Singh had indicated that some NGOs were protesting against the Kudankulam Nuclear Project at the instance of some foreign organisations, P. Muralidhar Rao, BJP National Secretary told reporters after attending the party's state level meeting here on Tuesday night.

Singh had in an interview to a magazine hinted that protests around Kudankulam were often funded by some NGOs based in the United States and Scandinavian countries.

The Prime Minister's statement must be based on some authentic information, Rao added.
