KING Charles has been plunged into a fresh row ahead of his trip Down Under -- over his refusal to eat Australia's favourite cake.

Charles, 75, has bravely paused cancer treatment for his first tour of Oz as ­monarch.

But all six of its state premiers snubbed an invite to join him at a reception.

One has taken a further swipe by accusing the King of turning down a Lamington.

Steven Miles said he and Charles visited a children's hospital in 2018 but the royal spurned the sponge dipped in chocolate and coconut, made by the kids.

The Queensland premier claimed: "I've got a bit to do here in Queensland so I won't be able to make the party with the King.

"But I did host him last time he was here in Queensland so I'm sure he won't take it personally.

"I took him to the children's hospital and we had a really great day there.

"The highlight was the children had made Lamingtons and he looked at me and I said 'we've got to eat it'.

"And he said 'I will not', so I ate the Lamington. He declined the Lamington but I ate it for him."
