There should be a law to prohibit such post poll, unethical alliances as happened in Karnataka. During election time political parties accuse opponents with charges of corruption, criminal & and anti-nationl activities. But after the election, they align with the same party purely for coming to power, telling "anything may happen in politics".
Is it not a fraud on the electorate who voted a particular party listening speeches made in election campaign? For example, Deve gowda accuse BJP of communalism and said his party is JD 'secular' and sought the public to vote them. After the electorate voted them beleiving in their secularism they join with the same party to form government. Why this action itself not considered as an electoral malpractice. Why not to derecognise such parties ??? someone can file a Public interest litigation in courts and bring an end to such mockery of democracy.
