Marking the first anniversary of the passage of three contentious farm laws as ‘Black Day’, scores of Shiromani Akali Dal workers led by their party president Sukhbir Singh Badal staged a protest march in the national capital on Friday.

The protest march was carried out from Gurudwara Rakab Ganj to the Parliament House.

The Delhi Police also detained Sukhbir Singh Badal, party leader Harsimrat Kaur Badal, and 11 others for organising a protest march without first obtaining permission from the authorities.
