Reiterating her demand for use of the ballot paper instead of the electronic voting machines (EVMs), West Bengal Chief Minister Mamata Banerjee said here on Saturday electoral reforms were must for ensuring transparency and preventing black money in polls.

Stating that she has been rooting for electoral reforms since 1995, Banerjee said, "For preventing black money (in polls), restoring democracy, ensuring transparency on the part of political parties, the reforms are a must. It should include state funding. Why should a party collect funds? Why should black money be there?".
