A High Court in Australia has ruled that Australia’s Deputy Prime Minister Barnaby Joyce and four other politicians were wrongly elected because they held dual citizenship.
The High Court of Australia decision means three of the politicians, including Joyce, are disqualified from office.
The others quit in July.
Australia's constitution prohibits dual citizens from being elected.
Joyce's exit puts pressure on the government, which only had a one‑seat majority when he was in office.
He could return through a by‑election.
The deputy prime minister, who renounced New Zealand citizenship in August, has pledged to re‑contest his lower house seat.
The other four politicians ‑ Fiona Nash, Malcolm Roberts, Larissa Waters and Scott Ludlam ‑ had been elected to the Senate.
