Australian senator quits over New Zealand dual citizenship – BBC News

May explain in part relatively low levels of diversity among Australian politicians although I suspect other factors more important:

An Australian senator has resigned after realising he holds dual citizenship, meaning his nine-year parliamentary career most likely breached the nation’s constitution.

Scott Ludlam, from the minor Greens party, said he only learned of his New Zealand citizenship last week.

Under Australia’s constitution, a person cannot run for federal office if they hold dual or plural citizenship.

Mr Ludlam had been told his eligibility would be challenged in court.

The senator, who was also Greens co-deputy leader, apologised for what he called an “avoidable oversight”.
