US presidential hopeful Donald Trump has been sharply criticised over lewd and sexually charged comments he made about women in 2005.

The former reality TV star bragged about kissing, groping and trying to have sex with women who were not his wife on recordings released by The Washington Post and NBC News on Friday.

The celebrity businessman boasted "when you're a star, they let you do it", in a conversation with Billy Bush, then a host of the television show "Access Hollywood", as he waited to make a cameo appearance on a soap opera 11 years ago.

The remarks were captured by a live microphone that Trump did not appear to know was recording their conversation.

OPINION: Clinton, Trump, and the ends of great power hypocrisy

The video's release comes out just two days before Trump will face his rival, Hillary Clinton, in their second presidential debate and as he confronts a series of stories about his past comments about women.

The 2005 remarks were recorded months after the reality TV star married his third wife, Melania. He is heard bemoaning that he tried and failed to seduce an unidentified woman, saying, "I moved on her and I failed, I'll admit."

"I did try and f--- her. She was married," Trump said. "And I moved on her very heavily. In fact, I took her out furniture shopping. She wanted to get some furniture. I said, 'I'll show you where they have some nice furniture.'"

Trump said he "moved on her like bitch" and then made a crass remark about the woman's breast implants. Then, after seeing the actress Arianne Zucker on the set of the soap opera on which he was to appear, he said he needed some breath mints "just in case I start kissing her".

"You know I'm automatically attracted to beautiful - I just start kissing them. It's like a magnet. Just kiss. I don't even wait," Trump said. "And when you're a star they let you do it. You can do anything." He added: "Grab them by the p----. You can do anything."

'I was wrong'

After the release of the video, Trump apologised via his Twitter page.

"I've never said I'm a perfect person, nor pretended to be someone that I'm not. I've said and done things I regret ... Anyone who knows me knows these words don't regret who I am. i said it, I was wrong and I apologise," he said in a filmed statement.

In a statement released earlier on Friday by his campaign, Trump described the incident as "locker room banter, a private conversation that took place many years ago. Bill Clinton has said far worse to me on the golf course - not even close. I apologise if anyone was offended".

Bill Schneider, a political analyst and professor of policy, government and international affairs at George Mason University, told Al Jazeera that Trump's words were "devastating" and "poisonous".

"Most Americans already think he's not qualified [to be US president] but this just confirms that," Schneider said. "If he stays in the race, that's his decision, but he's almost certain to lose."

Schneider added, however, that despite the blunder, Trump's "core supporters will probably stay with him".

'This is horrific'

The comments that appeared to condone sexual assault were swiftly condemned by Clinton's campaign and a number of Republicans.

"This is horrific. We cannot allow this man to become president," Clinton posted on her campaign's Twitter account. House Speaker Paul Ryan said he was "sickened by what I heard today".

Trump has a long history of making lewd and highly sexual comments toward and about women.

The Associated Press reported this week that during his years as a reality TV star on the "The Apprentice" the GOP nominee repeatedly demeaned women with sexist language, rating female contestants by the size of their breasts and talking about which ones he'd like to have sex with.

During frequent interviews with radio show host Howard Stern in the 1990s, Trump made a long list of demeaning comments, saying that he could have had sex with Diana, princess of Wales, who had recently been killed in a car crash, and declaring that, "a person who is very flat-chested is very hard to be a 10".

He has repeatedly called the comedian Rosie O'Donnell a "pig" and "slob" and suggested she would be less depressed if she stopped looking in the mirror. The Los Angeles Times reported last month that managers at Trump's golf club in southern California knew the New York developer only wanted good-looking women on staff.

The Republican nominee delivered an uneven performance in the first presidential debate - punctuated by his frequent interruptions of his female opponent - and then spent days after the debate renewing his past attacks on Alicia Machado, the 1995 winner of the Miss Universe pageant that Trump used to own, over her weight.
