Japan election: Abe set to win key upper house vote

Polls have opened in Japan for upper house elections expected to deliver a win for PM Shinzo Abe.

Half of the 242 seats in the chamber are up for grabs.

Polls show Mr Abe's Liberal Democratic Party (LDP) and its allies could secure a majority, meaning a ruling party would control both houses of parliament for the first time in six years.
