Hundreds of Congress workers today formed a human chain in New Delhi as part of their party's observance of November 8 as 'black day' on the first anniversary of the demonetisation of high value currency notes.

The Congress workers carried placards reading "Notebandi ne kiya prahar, thapp ho gaya karobar" (demonetisation hit hard forcing businesses to collapse), "Notebandi ne kiya vivash, 8 November kala diwas" (Demonetisation forced us to observe November 8 as Black day).
