Last week, when the Icelandic President Mr Guðn was answering questions from pupils at a school in Iceland's northern town of Akureyi, Mr Guðni was asked by a bold student for his thoughts on pineapple pizza.

He answered this deeply divisive question by saying he was "fundamentally opposed to the idea, going as far as to say he would ban the tropical fruit from pizza if he could." Understandably, the storm of debate erupted with fans and opponents taking to chat groups, newspapers and TV to air their opinions.

Whether or not it could actually be banned was out of the question, the President later clarified. "I like pineapple, just not on pizza. I do not have the power to make laws which forbid people to put pineapples on their pizza. I am glad that I do not hold such power." Presidents should "not have unlimited power", he continued. "I would not want to hold this position if I could pass laws forbidding that which I don't like. I would not want to live in such a country. For pizza, I recommend seafood."

Love it or hate it, pineapple on pizza is a combination created in Canada, according to the country's prime minister. Trudeau made the statement on Twitter- a stand which could equally lose or gain him fans as well.

Both world leaders caused a stir on social media as others weighed in on the debate - a discussion which does not look close to being settled any time soon.
