Chris Smith's contract terminated by 2GB and Sky News over Christmas party allegations

Broadcaster Chris Smith has been sacked by radio station 2GB and TV network Sky News after allegations of misconduct at a work Christmas party.

2GB issued a statement earlier confirming the Nine radio station had terminated Smith's services.

"The termination follows the Sky News Christmas party at the weekend, where Chris has conceded his behaviour was unacceptable, 'apologising profusely' for his 'drunken treatment' of women," the statement read.

Nine's managing director of radio Tom Malone said: "Chris' behaviour represents a serious breach of his contract and is not aligned with the values of 2GB."

The statement said Nine has "provided support to Chris in recent days and will continue to offer that support as required".

Sky News Australia CEO Paul Whittaker said in a statement Smith's contract has been terminated over allegations of "serious misconduct".

"Following an investigation into allegations of serious misconduct, we have today advised Chris Smith that his contract with Sky News Australia has been terminated as a result of inappropriate behaviour that is in breach of his contract and company policy," Whittaker's statement read.

"We continue to offer support to affected staff members whose welfare remains our primary concern."

The TV station had previously suspended Smith over the alleged misconduct.

On Monday, Smith apologised for his behaviour and said he was "in a facility receiving professional help, to deal conclusively with my abuse of alcohol".

"I am beyond gutted and devastated to know I have upset my colleagues after our Christmas party," he said.

"I apologise profusely to the women I upset.

"That's not the man I am at work ever, as they will all attest.

"They have been so supportive to me and do not deserve such drunken treatment."

Nine, the publisher of this website, also owns 2GB.
