So Prince Charles is to walk Meghan Markle down the aisle at today's royal wedding.
It was neither here nor there to me until a couple of days ago it was suggested that Markle's mother, Doria Ragland, may be the one to "give her daughter away".
Although the tradition has objectionable origins (selling a daughter to the highest bidder), there is something beguiling about the sight of a big, bluff bloke looking tearful as he walks his little girl down the aisle.
And when the father and daughter relationship has been strong, it seems appropriate that a bride should be delivered to her husband-to-be by the man who loved her first.
For Meghan Markle, however, the roles are different because her mother has been the more significant parent in her life.
