A top lawmaker from Australia's far-right One Nation party has grabbed headlines after exploding at a misbehaving dog as he was grilled on live TV. Former deputy prime minister Barnaby Joyce was being interviewed on national broadcaster ABC on Monday night when he interrupted the one-on-one to shriek "sit down!" The errant pooch then interrupted the proceedings again, with Joyce saying: "I do apologise for this dog, it's just started to bail up." Otherwise, this interview will come to a grinding halt, Sarah," Joyce snapped back. Opinion polls show One Nation, for decades a fringe group led by provocateur Hanson, has become Australia's most popular party in recent months.
