New Delhi: Union Home Minister Amit Shah is expected to introduce today's Citizenship Amendment Bill in the Lok Sabha, in the midst of opposition protests and widespread protests in the Northeast against what many of its citizens say is a bid to nullify a decades-old pact aimed at curbing illegal immigration. Shah will introduce this afternoon the bill to amend the six-decade-old Citizenship Act, after which it will be debated and passed. The bill seeks to promote the country's citizenship for non-Muslim refugees from Pakistan, Bangladesh and Afghanistan.
