Sometime in late 1960s, after a massive victory of the Congress in an election led by Indira Gandhi, the then Jana Sangh made allegation that elections were rigged. The Party President Balraj Madhok alleged that a special ink was brought from the then Soviet Union which could be easily erased after a voter casts his vote. He can, therefore, easily vote again. The allegation spread like wild fire and, it appeared, it was true. But when investigations were made, the allegation proved to be wrong, no erasable ink was brought from Soviet Union.
