Harry’s romance with Meghan – who he married last May – has reportedly changed the prince. It comes amid speculation of a rift between the Sussexes and the Cambridges, sparked by Meghan and Harry’s plans to move to Windsor.
Speaking on Channel 5 documentary Kate V Meghan: Princesses At War, Lady Colin Campbell said: “Everything I hear is that Harry is completely beguiled by Meghan and completely enthralled to her and has changed considerably.
“People do change when they get married.”
Meghan and Harry have faced rumours of tensions with Prince William and the Duchess of Cambridge since announcing their plans to move from Kensington Palace last November.
The claims have largely focussed on the duchesses, with reports of an incident over Princess Charlotte’s bridesmaid dress and a clash about staff.
Meghan has also faced questions about her behaviour, with Harry’s wife said to have been nicknamed “Duchess Difficult” by royal staff.
But royal author Katie Nicholl said the real feud could be between the brothers.
Ms Nicholl explained how William was concerned that Harry’s relationship with Meghan was moving too fast, leading him to have a word with his younger brother.
But Harry was “riled” by William’s intervention which he saw as “criticism” of his bride-to-be.
In an appearance on the Channel 5 documentary which aired on Sunday, Ms Nicholl said: “They will joke about who hasn’t done the washing up or William will have a go at Harry for eating him out of house and home but actually a rift over his choice of bride is far more serious.
“William was quite concerned that the relationship had moved so quickly and being close to Harry, probably the only person close enough to say to Harry ‘this seems to be moving quickly, are you sure?’
“And I think what was meant as well intended brotherly advice just riled Harry.
“Harry is hugely protective of Meghan, he saw that as criticism, he interpreted that as his brother not really being behind this marriage and I don’t think things have been quite right ever since.”
Meghan and Harry met in July 2016 after being introduced by a mutual friend.
The pair embarked on a long-distance relationship, with Meghan based in Toronto, Canada, to film US legal drama Suits.
The loved-up couple went on to announce their engagement in November 2017, marrying the next May.
And Meghan is expecting their first child in the spring.
