Read the passage and answer the question:

Opposition parties were in the forefront of organising public protests and pressurising the government. Parties opposed to the Congress realised that the division of their votes kept the Congress in power. Thus parties that were entirely different and disparate in their programmes and ideology got together to form anti-Congress fronts in some states and entered into electoral adjustments of sharing seats in others. They felt that the inexperience of Indira Gandhi and the internal factionalism within the Congress provided them an opportunity to topple the Congress. The socialist leader Ram Manohar Lohia gave this strategy the name of ‘non-Congressism’. He also produced a theoretical argument in its defence: Congress rule was undemocratic and opposed to the interests of ordinary poor people; therefore, the coming together of the non-Congress parties was necessary for reclaiming democracy for the people.
