The last phase of polling in Uttar Pradesh and Manipur is on March 8. But following the demise of two candidates in the Alapur (UP) and the Karnaprayag (Uttarakhand) constituencies, the Commission had postponed elections there and fixed March 9 as the new date.
If candidates of recognised parties-- in this case the SP and the BSP-- die before or on polling day, the election is postponed to allow the party field a new person.
According to election laws, exit polls can be telecast half-an-hour after the end of polling in all the phases and states.
