It's election day in Tonga, with about 64,000 Tongans registered to vote. They will be electing 17 People's Representatives for the 26 member legislature. Tonga - a Pacific country of slightly more than 100,000 people - is a constitutional monarchy and this marks the fourth election since its political system underwent major reforms in 2010.
