William reportedly had one key question about Meghan in the run-up to the royal wedding
"I don’t think things have been quite right ever since."
As rumours of a 'feud' between Meghan Markle and Kate Middleton continue, it looks as though we may have missed the real falling-out - a rift between Princes Harry and William.
Royal biographer Kate Nicholl has claimed that things soured between the brothers when William asked Harry whether his relationship with Meghan was moving too fast.
The couple met in the summer of 2016, were engaged less than a year and a half later and married within two years of when they started dating.
What William meant as concern for Harry, Ms Nicholl said, left Harry annoyed.
"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," she said on Channel 5 documentary Kate V Meghan: Princesses At War.
“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.”
