Creating a Centre-state combined Goods and Services Tax (GST), as we now find from the nature of negotiations, will be like sowing the seeds of a perennial political potboiler. Negotiations have reached a cul-de -sac. It is not a question of delay any more .
If the Centre concedes everything that the increasingly demanding states insist upon , GST will be so fractured that it will neither achieve a common market nor simplicity, nor revenue buoyancy.
