Nearly 20 000 people have been improperly registered as voters for this week’s urban council and parliamentary by-elections, while another 1 700 who voted last year and in 2000 are missing from the voters’ roll, according to figures released by the Movement for Democratic Change (MDC). MDC director of elections Remus Makuwaza said the 1 700 voters whose names were missing from the voters’ roll were discovered in Harare Central constituency alone.
