"Christian missionaries control the Congress. Sonia Gandhi, the mother of Congress president Rahul Gandhi works on the directions of these missionaries. These missionaries are a threat for the unity of the country," Singh said while talking to reporters on Saturday.
Singh also alleged that the democracy in the north eastern states of the country has "weakened" due to "conversion of people there into Christianity."
"The North-East is under the influence of Christian missionaries. Democracy has weakened due to conversion of people into Christianity there. The conspiracies hatched by these missionaries are threat for the country," he added.
The Ballia MP, incidentally, had also alleged recently that the Christian missionaries were behind the vandalisation of the statues of the Dalit icon and key architect of the Indian Constitution, Dr Bhim Rao Ambedkar.
Singh further said after the Supreme Court's decision on Justice BH Loya case, Rahul Gandhi should regret his stand.
