Jon Snow to end up on Iron Throne: PM

According to Malcolm Turnbull, Barnaby Joyce will win his citizenship case, the High Court will give the same-sex marriage survey a nod of approval and energy prices will be lower under his government.

But the prime minister's biggest call has got to be is that Jon Snow will end up on the Iron Throne.

Yes, Malcolm is a Game of Thrones fan.

Asked by Jodi and Soda and Adelaide radio station Mix 102.3 whether he is disappointed singer-songwriter Ed Sheeran won't be making another cameo performance in the fantasy drama, Mr Turnbull said: "I guess so."

"I'm more interested in what happens to that ice dragon in the next series. He's gonna do some bad stuff I think," he said.

"I predict that Jon Snow will end up on the Iron Throne."

Sadly, fans will have to wait until 2019 when the eighth and final series is released to find out if he is correct.
