Speaking to Fabulous, the royal author said of Charles: 'I think he likes strong women, but in The Firm there is only room for one Queen.'

Comparing their popularity to that of Andrew and Fergie when they met, he added: 'I think he foresaw considerable problems ahead for The Firm. 

'For the sake of The Firm he will feel this outcome is better that the monarchy is small in size rather than a constellation of stars in separate orbits.'

Palace insiders reported that a close relationship developed between Charles and Meghan after he walked her down the aisle in 2018, with the two sharing an interest in art, culture and history.

Prince Charles is reportedly a fan of Meghan Markle, and a source told the Mail On Sunday previously that he gave the Duchess of Sussex the Royal nickname ‘Tungsten'.

According to the insider, the name was given because she is 'tough and unbending', just like the very strong metal – and the affectionate name stuck. 

The insider said at the time: ‘Prince Charles admires Meghan for her strength and the backbone she gives Harry, who needs a tungsten-type figure in his life as he can be a bit of a softy. It’s become a term of endearment.’ 

The reports come after Lady Colin Campbell claimed the Queen welcomed Meghan into the royal fold, due to her mixed-race heritage.

In an extract seen by FEMAIL, Lady Colin Campbell claimed the Queen felt Meghan's biracial identity 'made the monarchy both reflective and representative of multicultural, multiracial Britain in a way that a white California-born actress who had been a cast member of a popular television series could never have'.  

She continued: 'As a prince once told me, "Had Meghan not been a woman of colour, they would never have allowed the marriage. It was the only thing that was unreservedly in her favour".'
