UCC is a proposal to have one common set of personal laws for all citizens in India, covering marriage, divorce, inheritance, and adoption, regardless of religion. It aims to ensure equality before law and promote national integration by replacing religion-based personal laws with a uniform legal framework. In the Bengal polls, where BJP strives to wrest power from three-time chief minister Mamata Banerjee, who fiercely opposes the UCC, the issue is expected to highly polarise the elections.
