Australia's deputy PM disqualified from office

Australia's deputy prime minister was wrongly elected because he held dual citizenship, the High Court of Australia has ruled.

Four other politicians were also invalidly elected in July last year, the court said.

Australia's constitution prohibits dual citizens from standing for office.

Deputy PM Barnaby Joyce's exit strips the government of its one-seat majority, but he could return following a likely by-election.
