It was moist. It was marzipan. And it was a fruit cake. Deputy Leader of the Nationals, Nigel Scullion, has taken out the celebrity bake-off at the Darwin Show.

But what raised some eyebrows were the decorations on top - a large saltwater crocodile and Prime Minister Julia Gillard - with the saurian apparently devouring the PM, starting with her right arm.

A spokesman for Senator Scullion has denied the cake depicted Ms Gillard being eaten.

"The croc has got her by the arm - crocs being nice, warm, caring creatures it could be seen that he's taking her for a swim," the spokesman told ABC News Online.

The spokesman said his boss is a very talented cake-baker - having taken out prizes at the Alice Springs and Katherine shows - and deserved the win, which he shared with a group of kids.

"I reckon it was really good. The croc had all its spines, Julia Gillard was immediately recognisable and he got a good likeness of the Prime Minister, not like cartoonists who give her a long nose and an elephant's bum.

"It was a fruit cake. The crocodile spines were made out of frosting so the spines would stay up. The Prime Minister was made out of marzipan. Senator Scullion made it 100 per cent himself."

The spokesman said the cake was in high demand and he almost missed out on the treat.

"By the time I got there the cake was almost consumed but I didn't eat any of the Prime Minister, I had a bit of the crocs tail. It was very moist and I'm very fussy - my mum cooks the best fruit cake in the universe," he said.

"It was a bit of fun - this is the Northern Territory. The Northern Territory News can't sell a paper unless it has a croc on the front. Today it has two - 'Cannibal croc gets up close and personal' and 'Croc bites swimmer.' The cake only made page six.

"It's a comical take on a political theme, a storm in a tea cup. You've got to admit the man's got some talent in making and decorating cakes.

"There was no malice intended. It was done in a light-hearted fashion befitting the occasion."

A spokesman for Ms Gillard said she was "disappointed Senator Scullion didn't save her a slice."

And if you thought Senator Scullion is a one-trick, cake-baking pony - according the his spokesman, he is not.

"He's quite an adept hand at cooking a curry. Sometime he brings in a big pot for our lunch."
