Mary McCartney splits from husband2005-04-12 08:00:01
Television producer Alistair Donald had been "plagued by feelings of inadequacy" living in the shadow of his photographer wife and her famous family, according to a close friend.
Their marriage difficulties were also compounded by Mary's rocketing career after she was commissioned to take the first official portrait of British Prime Minister Tony Blair's youngest son, Leo.
A friend told Britain's Daily Mail newspaper: "Alistair has had problems with work and has been unable to establish himself as a television producer. In contrast his wife's career has taken off.
"Also, the cost of renovations to their new home has been extortionate and unbelievably problematic; this has been a constant source of tension for the couple."
Mary, 35, has remained in the couple's West London family home with their two sons, Arthur, five, and Elliot, two.
Alistair, meanwhile, has moved into the house the couple recently bought on the other side of the capital.
The pair say the split is temporary and they are keen to reconcile their differences for the sake of their children.
McCartney's friend added: "Both Mary and Alistair are desperate to sort out their differences and neither view the split as a permanent thing."
The couple married in a small church wedding in September 1998 close to Sir Paul's countryside estate in Rye, East Sussex.
