KUALA LUMPUR • As Malaysia's election campaign enters its final stretch before Polling Day on May 9, there are concerns that the country's political and economic stability are at stake.

There are many unknowns heading into the most keenly contested general election, where nearly 15 million Malaysians will decide on who they want to represent them in the 222 seats in the federal Parliament and 505 state assembly seats in 12 states. State assembly elections are held separately in Sarawak.
