OPTIONS: Theresa May, Piers Morgan, Prince Harry
ANSWER: Theresa May
As if Theresa May was not in enough of a jam over Brexit, she has now sparked a debate about how to handle actual jam - the kind that comes in jars.
It comes after she reportedly told cabinet ministers she scrapes the mould off the fruit preserve rather than throw it away.
The SNP's Pete Wishart picked up on the PM's comment on Twitter, saying it was "a bit like she runs the Tory Party".
The PM reportedly made the comments in a cabinet discussion on food waste.
The prime minister told colleagues that she scrapes the mould off and the rest is "perfectly edible", according to the Daily Mail.
She added that people should use "common sense" to work out if the whole jar should be thrown out.

In a triangle, the largest angle is four times the size of the smallest angle. The third angle is 24o bigger than the smallest angle.
Write an equation and solve it to find the size of each angle in the triangle
