The national capital is expected to witness fiery rallies by UP CM Yogi Adityanath, a star campaigner for the BJP, and his rivals from the Congress-top-leadership in the run-up to the assembly-elections next-week. While Yogi Adityanath will hold rallies between Saturday and Tuesday at venues ranging from Shaheen Bagh to Rohini, Congress-president Sonia Gandhi will address a public gathering in Shastri Park on Wednesday.
