New Delhi has banned the use of plastic bags in all shops, starting very soon. Notification has been sent out to all shopkeepers, and they are being given 10 to 12 days to fall into line. After that, traders will have to pay a penalty or spend five years in prison (what!). That's the new law that the Delhi government says it is ready to enforce. Civil servants said that punitive measures were needed after another law prohibiting plastic bags was ignored. However they do accept that the new ban will have to be implemented slowly.
