LILONGWE, Malawi (AP), May 19 (TIWN) — Corruption and the need for economic growth are the main campaign issues as Malawi goes to the polls Tuesday for a presidential election that pits the incumbent against his own vice president as well as the country's main opposition party.

The need to protect people with albinism has also emerged as a hot election topic in this southern African country.

More than 6 million people are registered to vote in the elections that also will decide 193 parliamentary seats in one of the world's poorest countries. As in previous elections, the results of the presidential vote likely will be challenged in court.

Although seven candidates are running for president, just three are seen as having a chance at winning. As Malawi has no runoff election, whoever receives the most votes wins, even if the share is well below 50%.

The 78-year-old President Peter Mutharika of the ruling Democratic Progressive Party is up against 46-year-old Vice President Saulos Chilima of the United Transformation Movement and main opposition Malawi Congress Party leader Lazarus Chakwera, 64

Former president Joyce Banda has dropped out of the race and is supporting Chakwera via a coalition with her People's Party.
