Business tycoon Donald Trump is endorsing his Celtic roots by becoming an ambassador for Scotland. THE APPRENTICE star, who is half Scottish and half German, is thrilled with the honour, which will see him act as a representative for the British country on behalf of First Minister JACK MCCONNELL. And, despite opposition from environmentalists, Trump confirms he's determined to invest in a $525 million (GBP300 million) golf course outside the Scottish city of Aberdeen. He says, "As an international businessman, I've enjoyed success over the years and I like to think that part of my achievement can be attributed to my Scottish roots." MCConnell adds, "Donald is a globally recognised figure who can help us to promote Scotland. I am delighted that he has taken up my offer."
