TROUBLED WA Opposition leader Troy Buswell has broken down in tears at a press conference and admitted he sniffed the chair of a female Liberal Party staffer.

With tears in his eyes, Mr Buswell had to compose himself before telling the media in Mandurah this morning that his behaviour had been unacceptable.

Mr Buswell said he had repeatedly refused to deny the allegations because he wanted to protect the woman involved.

But he broke down after he was asked about the effect of the reports on his wife and children.

With tears in his eyes, Mr Buswell said he needed a short break, turned his back and then asked his press secretary to bring him a glass of water.
