But, no political party will vote for such an amendment. We must have to live with it.
Even better would be the presidential system of government. Here, irrespective of the strength of the Parties in Parliament, threat of destabilisation will never come. And automatically, smaller parties, including regional parties, would wane away from national politics.
Even here, no parties will vote for it. When Indira Gandhi could not do it, no one else can do it in near future, at least.
