Keith Holyoake vs Olafur Ragnar Grimsson

Holyoake became prime minister after the resignation of Walter Nash. He led the National Party and would go on to serve as prime minister for over 11 years, becoming one of New Zealand's longest-serving leaders.

Holyoake's government committed New Zealand combat troops to the Vietnam War in support of the United States. The decision was controversial and led to anti-war protests, but Holyoake argued it was necessary to maintain the alliance with the US.

Holyoake's government signed the New Zealand-Australia Free Trade Agreement (NAFTA), reducing tariffs and promoting economic integration between the two countries. This agreement laid the groundwork for the later Closer Economic Relations (CER) agreement.

Holyoake resigned as prime minister, handing over leadership to Jack Marshall. His resignation marked the end of a long political career, during which he had been a dominant figure in New Zealand politics.

Olafur Ragnar Grimsson was elected President of Iceland, succeeding Vigdis Finnbogadottir. He won with 41.4% of the vote. His presidency began a period of 20 years in office, making him one of Europe's longest-serving heads of state.

Grimsson refused to sign a media ownership bill passed by parliament, triggering a national referendum. The bill aimed to restrict media ownership. Voters rejected the bill in the referendum. This was the first time a president used the veto power since Iceland's independence.

Grimsson was re-elected President of Iceland unopposed as no other candidate qualified for the ballot. This occurred during the 2008 financial crisis that severely impacted Iceland. His unopposed re-election reflected political consensus during a national emergency.

Grimsson announced he would not seek re-election after 20 years as president. His decision followed the Panama Papers scandal, in which his wife was implicated. He left office in August 2016, ending the longest presidential tenure in Iceland's history.
