<P> However, former Canadian Prime Minister John Turner was born in the United Kingdom and still retains his dual citizenship . Stéphane Dion, former head of the Liberal Party of Canada and the previous leader of the official opposition, holds dual citizenship with France as a result of his mother's nationality; Dion nonetheless indicated a willingness to renounce French citizenship if a significant number of Canadians viewed it negatively . Thomas Mulcair, Leader of the New Democratic Party and former leader of Official Opposition in the Canadian House of Commons also holds dual citizenship with France . </P> <P> In Egypt, dual citizens cannot be elected to Parliament . </P> <P> The Constitution of Australia, in Section 44 (i), explicitly forbids people who hold allegiance to foreign powers from sitting in the parliament of Australia . This restriction on people with dual or multiple citizenship being members of parliament does not apply to the state parliaments, and the regulations vary by state . A court case (see Sue v Hill) determined that the UK is a foreign power for purposes of this section of the constitution, despite Australia holding a common nationality with it at the time that the Constitution was written, and that Senator - elect Heather Hill had not been duly elected to the national parliament because at the time of her election she was a subject or citizen of a foreign power . However, the High Court of Australia also ruled that dual citizenship on its own would not be enough to disqualify someone from validly sitting in Parliament . The individual circumstances of the non-Australian citizenship must be looked at although the person must make a reasonable effort to renounce his or her non-Australian citizenship . However, if that other citizenship cannot be reasonably revoked (for example, if it is impossible under the laws of the other country or impossible in practice because it requires an extremely difficult revocation process), then that person will not be disqualified from sitting in Parliament . In the 2017 Australian parliamentary eligibility crisis, the High Court disqualified Australia's Deputy Prime Minister and four Senators because they held dual citizenship, despite being unaware of their citizenship status when elected . </P> <P> In New Zealand, controversy arose in 2003 when Labour MP Harry Duynhoven applied to renew his citizenship of the Netherlands . Duynhoven, the New Zealand - born son of a Dutch - born father, had possessed dual citizenship from birth but had temporarily lost his Dutch citizenship due to a 1995 change in Dutch law regarding non-residents . While New Zealand's Electoral Act allowed candidates with dual citizenship to be elected as MPs, Section 55 of the Act stated that an MP who applied for citizenship of a foreign power after taking office would forfeit his / her seat . This was regarded by many as a technicality, however; and Duynhoven, with his large electoral majority, was almost certain to re-enter Parliament in the event of a by - election . As such, the Labour Government retrospectively amended the Act, thus enabling Duynhoven to retain his seat . The amendment, nicknamed "Harry's Law", was passed by a majority of 61 votes to 56 . The revised Act allows exceptions to Section 55 on the grounds of an MP's country / place of birth, descent, or renewing a foreign passport issued before the MP took office . </P>
