The dual citizenship crisis that has rocked Australia's parliament took another twist on Tuesday, with a senior member of the governing Liberal Party saying he may have to quit Parliament.
Stephen Parry, a senator who is president of Australia's upper house, said he has contacted authorities in the United Kingdom to check if he holds dual citizenship because of his British-born father.
He would be the latest lawmaker found to have breached of an obscure clause in the nation's constitution that bans lawmakers from holding dual citizenship.
The High Court on Friday disqualified five lawmakers from sitting in Parliament on the grounds that they were citizens of both Australia and another country, a breach of the clause that only came to light in July.
The five included Deputy Prime Minister Barnaby Joyce, the leader of the National Party, the junior partner in Liberal's ruling coalition. Joyce has renounced the New Zealand citizenship he inherited from his father but still must win a by-election if he wants to return to his seat.
