Voting begins in Thai election - but will General Chan-o-cha maintain power?

Thailand is going through a general election and early voting has begun. The 500 members of its House of Representatives will be elected, and then vote jointly with the Senate to choose the Prime Minister. This could be the end of incumbent Prayut Chan-O-Cha's grip on power, which he held thanks to the support of a military junta for nine years. But the daughter of a prominent political family is out to challenge him.
