Taiwan's three presidential candidates are on their final campaign push before the island goes to the polls on Saturday.

President Ma Ying-jeou, seeking a second term, is neck-and-neck with opposition leader and Taiwan's first female presidential candidate, Tsai Ing-wen.

A third contender is James Soong, who observers say could take votes away from Mr Ma.

The race is being closely watched, not least by China and the United States.
