A millionaire Scottish businessman has pledged to donate £6m to Bob Geldof's Band Aid appeal.
Mr Hunter will match sale proceeds of the charity song
Tom Hunter said he will match pound for pound every future sale of the remixed song, "Do they know it's Christmas?", raising money for aid relief in Sudan.
The hand-out from his Hunter Foundation is the single largest donation to the appeal.
Mr Hunter's charitable foundation is giving a further million pounds to a campaign group fighting world poverty.
The tycoon said he was moved to act by a television documentary which suggested that things had barely improved since 1984, the year when Band Aid first topped the UK charts.
"We do have a real chance to eradicate world poverty in our lifetime," he said.
"We can make a difference and with the G8 meeting in Gleneagles next year, we need to let the world know the situation needs to change.
"I'd been watching a documentary at home and what was striking for me was how little things had actually changed.
"Everyone who works there and the people behind the first Band Aid all worked with the best intentions and the current plans are very good, but we all need to do our bit."
Mr Hunter's donation follows the £105m he gave to charity last year - one-fifth of his fortune.
This was used to set up the Hunter Foundation, which encourages young people in Scotland to be entrepreneurial.
The new version of the Band Aid song features vocals from Coldplay's Chris Martin, U2's Bono, Kylie Minogue, Dido, Robbie Williams and the Sugababes.
Proceeds from the sales of the single, and Mr Hunter's contribution, will go towards aid relief in Africa in countries such as Ethiopia and Sudan.
The money raised will also be used to help combat HIV and AIDS across the continent.
