New South Wales Premier Barry O'Farrell has been accused of winking at a Labor MP.

In State Parliament this afternoon, Deputy Opposition Leader Linda Burney rose on a point of order during Question Time to ask Mr O'Farrell to stop winking at her, saying it was not attractive.

The Premier did not offer a defence.

"If the Member for Canterbury is offended by my eye, Madam Speaker, I take it back, I withdraw it," he said.

"But it's been a long time since I winked at a woman other than my wife," he added to the cheers of fellow MPs.

But Ms Burney was not placated and she took to the airwaves to complain about the Premier's "unstatesmanlike" capers.

"It's the bear pit and I give as good as I get, but I don't appreciate being winked at not once, but twice, and almost a third time, by the Premier," she told Macquarie Radio.

"It's arrogant, it's silly and it's smug.

"I tell you what, if Barry O'Farrell was my husband I wouldn't be real impressed. So I will leave it up to him and Rosemary to sort out."

Ms Burney said the Premier's almost three winks were designed to "get under her skin" and allowed him to sidestep her questions about the planned Sydney north-west rail link.

Asked what sort of wink the Premier had used, Ms Burney said: "It was a big smile on his face, it was very deliberate, it was very definite."
