Thailand may have its first female Prime Minister after the country's largest opposition party won the general election.

The leader of the Pheu Thai party is Yingluck Shinawatra, the youngest sister of Thaksin Shinawatra, a former prime minister.

Five years ago, her brother was removed from office in a coup.

Despite a clear-cut winner being declared on Sunday, politics in Thailand can be a dirty game and many questions remain.
