Alex Arthur, former WBO featherweight champion and Commonwealth Games Gold medalists said it was wrong for David Cameron to lecture people in Scotland about why they should stay in the UK.
In a statement to ITV News following Cameron's impassioned plea for unity, he said:
"The proudest moment in my career is winning the gold medal at the Commonwealth Games in Kuala Lumpur for the sole fact that I won it for Scotland and I won it wearing the blue vest. If we were an independent nation we could also be competing at the Olympics.
"I’ve boxed all over the world including countries like Denmark, Norway, Switzerland and Sweden. They’re all small countries, most of them with less than 10 million people, and they’re absolutely fine.
"I believe that we’d be a better country if we were independent, I think we can definitely look after ourselves and I think it’s better for the future of our youth and our people that we vote Yes in September.
‘It’s wrong of David Cameron to lecture people in Scotland. He should debate with us instead."
