Union Home Minister and BJP leader Amit Shah has taken a dig at Aam Aadmi Party (AAP) Arvind Kejriwal over the "unfulfilled promise" of cleaning up the Delhi stretch of River Yamuna to make it look like Britain's River Thames.
With voting in the Delhi assembly election less than two weeks away, Mr Shah aimed for one of the weakest points of the national capital - pollution, both air and water.
"He [Mr Kejriwal] promised he would purify River Yamuna in seven years and modify it just like London's River Thames," Mr Shah said at a rally.
