Andy Murray's mum left his father when both boys (he has a brother) were very young and the father had to bring them up.
She was Scottish National Tennis coach at the time.
The father has given a number of interviews (search the web) where he feels the mother is only interested in the boys now they are doing well at tennis.
The father thinks she is a glory hunter.
He does attend some matches at Wimbledon but as few people know what he looks like he is rarely featured in TV shots.
