The Mail says Prince Charles feels he has become 'peripheral' in two-year-old Prince George's life because of the 'Middletonisation' of his son William's life.
The columnist writes: "In fact, so vexed is Charles about the so-called 'March of the Middletons' that he has complained to friends: 'They never let me see my grandson.'"
The paper quotes a source saying: "Carole has rather taken over, dictating when George naps, when and what he eats. All in all, behaving like she's Queen Carole."
However, when asked about the last time Charles had seen grandson George, a Clarence House spokesman issued a statement, saying: "We would not comment on the specifics of private arrangements.
"His Royal Highness enjoys an excellent relationship with his grandson."
According to the paper, there have been 'few, if any' trips to Charles's Gloucestershire home Highgrove over the past year.The columnist states: "Some think it's a deliberate move on William's part to protect his young family from suffering the same stiff, and often unhappy, upbringing he endured."
Most of William and Kate's time is spent at their Norfolk home, Anmer Hall, on the Queen's Sandringham estate, where the Prince has been busy revising for his Air Transport Pilot's Licence.
The Middletons are frequent visitors and play an active role in the household. They stayed there over Christmas, when William pointedly hosted lunch for them on Christmas Day rather than eat with the Queen, as is traditional.
