A SOUTH African man who was switched at birth has revealed he resents his mum for not swapping him back because he grew up dirt poor while the other kid was rich.

Robin was raised by Sandy Dawkins, a single mum struggling to make ends meet living on the outskirts of Johannesburg, while Gavin was raised by wealthier parent Megs Clinton Parker in Pietermaritzburg, after they were switched at birth in 1989.
