The polling to select a single presidential candidate between the Millennium Democratic Party's Roh Mu-hyun and Chung Mong-joon of the National Alliance 21 began Sunday, with results expected early Monday at the earliest. If the poll fails to meet the criterion selected by the two sides then another survey will be taken, prior to the November 27 deadline for registering as a candidate.

Insiders say there could be a problem with the poll as a relatively unknown company is being used because the five major polling agencies refused to be used for political purposes. (Hong Young-lim, ylhong@chosun.com )
