A wave of disbelief was felt across the world today after John Key's out-of-the-blue resignation. Here are the top 10 reactions to the soon to be former PM's shock announcement.

Key's resignation was widely picked up by international media including The Guardian, CNN and BBC who published the news on their home pages.

The PM's son and DJ, Max Key, posted a tribute to his Dad on Facebook and Instagram, along with a family snap.

Today marks the end of an era. To say that I'm proud of you would be an understatement. You achieved your childhood...
