The BJP has urged Congress leaders Rahul Gandhi and Sonia Gandhi to return 51 cartons of correspondence belonging to former Prime Minister Jawaharlal Nehru to the Prime Ministers' Museum and Library (PMML). BJP spokesperson CR Kesavan alleged that the documents, donated to the institution in 1971, were taken back by Sonia Gandhi in 2008. The papers reportedly include letters exchanged between Nehru and Edwina Mountbatten, among other prominent figures.
