Barnaby Joyce is the deputy Prime Minister, leader of the National (country) Party, one of the two parties in the ruling right-wing coalition government of Australia. He has fallen foul of section 44 of the constitution, which forbids any member of the House or the Senate from being a dual citizen. Turns out he's a New Zealand citizen as well as an Ozzie citizen. The birds are kiwis, a flightless bird from NZ, which is also what Ozzies call their cousins from across the Tasman Sea.

Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.
