Narrative:

While on approach we encountered icing conditions on the approach. Warning system started going off. Approach asked us to slow multiple times but since unreliable airspeed was on captain's side we were correcting airspeeds on his side then started getting more bells. We started to complete QRH but we were being directed at the same time trying to figure out which side was correct. We informed approach on the problem and completed verification of the problem side. We transferred controls to first officer side and completed the approach and landing with no further issues. Threat icing conditions; threats close proximity on approach to final approach fix; threat trying to run QRH and verifying good side while on close final; threat airspeed indicating 160 and really doing 260. [Lesson] learned from this would be to cancel approach clearance; get vector heading and work the problem with more time and the controller not yacking in your ear continuously after making him aware of our discrepancy in airspeed; and him to continue to issue slower speeds to us; while continuing the approach.

Narrative: While on approach we encountered icing conditions on the approach. Warning system started going off. Approach asked us to slow multiple times but since unreliable airspeed was on Captain's side we were correcting airspeeds on his side then started getting more bells. We started to complete QRH but we were being directed at the same time trying to figure out which side was correct. We informed Approach on the problem and completed verification of the problem side. We transferred controls to FO side and completed the approach and landing with no further issues. Threat icing conditions; Threats close proximity on approach to final approach fix; Threat trying to run QRH and verifying good side while on close final; Threat airspeed indicating 160 and really doing 260.
