The Queensland leader of the Australian One Nation Party has resigned after lewd footage emerged of him in a US strip club groping a dancer.
Australian television show A Current Affair broadcast the footage on Monday night, showing Steve Dickson in a Washington D.C strip club last year.

The footage shows Dickson, who is married, groping a woman's breasts and making disparaging results about females, such as "I've done more Asian than I know what to do with".
On Tuesday morning, Dickson offered up his resignation, saying it did not reflect who he was.
"It shows a person who was drunk and not in control of his actions and I take full responsibility for allowing that to happen," he said in a statement.
Dickson said he had explained his actions to his wife the day after the encounter and she stood by him.
"I am also deeply remorseful for my disrespectful comments towards women.
"I found the footage difficult to watch as my words and actions under intoxication and in that environment are not a true reflection of myself."
One Nation leader Pauline Hanson accepted his resignation and said while strip clubs were legal businesses, Dickson's behaviour had been unacceptable.
"I have always spoken very highly of Steve Dickson, but the footage I saw last night cannot be ignored or condoned," she said.
The footage was secretly filmed by the same Al Jazeera video crew that filmed him discussing guns with the American gun lobby. That was a part of an investigation published earlier this year into One Nation's relationship with international gun advocates.
But A Current Affair was leaked the strip club footage, with Al Jazeera saying it didn't authorise its use.
