Australian senator Nick Xenophon has contacted the UK Home Office to clarify whether he holds a dual citizenship.
The senator said he would publically reveal the documents he receives back from the UK government as soon as possible, predicting he would have an answer by early next week.
“What can I do? I am making the enquiries,” Senator Xenophon said on Friday.
“As soon as I get that paperwork I will give it to you all.”
Mr Xenophon, whose Nick Xenophon Team controls three seats in the Senate, has spent the past week denying any dual citizenship concerns despite having a Greek mother and a Cypriot father.
He said he wrote letters to renounce any citizenship to the Greek embassy and Cypriot high commission in 2007, before he entered the federal parliament.
“I have never had citizenship of another country, never wanted citizenship of another country,” he said earlier in the week.
But Senator Xenophon’s father Theodoros Xenophou may have left Cyprus for Australia when the country was still a British colony, raising the prospect that Mr Xenophon may have inherited UK citizenship by descent.
