Many think putting pineapple on pizza is disgusting and an affront to Italian cuisine.

However, the Prime Minister of New Zealand has faced calls for impeachment over his chosen pizza toppings; pineapple and perhaps more controversially tinned spaghetti.

He wrote: "Cooked dinner for the family last night - like if you agree with tinned spaghetti on pizza!"

However, he later conceded the pizza was "soggy", writing: "I drained off some of the liquid but not quite enough since pizza was a bit soggy in the middle. Goes well with pineapple."
