Prince Harry and Meghan Markle‘s wedding day, it was claimed this week.

Lady Elizabeth Anson, a great-niece of the Queen Mother and a goddaughter of King George VI, was Her Majesty’s party-planner and confidant for many years.

Now, her words have been reported by journalist and royal biographer Sally Bedell Smith in her Substack ‘Royal Extras’, describing her private conversations with Lady Elizabeth, who was fondly called Liza by friends.

Liza claimed that Meghan was ‘full of charm’ and appeared ‘natural, intelligent, and thoughtful’ after she became engaged to Harry in 2017.

But as the wedding came closer, Liza claimed that both Harry and Meghan upset the Queen. Harry was apparently ‘rude’ to his grandmother for ten minutes in one meeting. Meghan allegedly refused to share details of her wedding dress with the monarch.

Speaking on the YouTube show Palace Confidential, Rebecca English, the Daily Mail’s Royal Editor, said: ‘I know from my own sources that the Queen was bemused and saddened by some of Meghan’s behaviour but by their behaviour as a couple.

‘It did overshadow her last few years of life, of course.’

But there was another reason why the Queen was reportedly ‘not at all content’ while sat in the pews at St George’s Chapel on May 19, 2018.

Ms Bedell Smith wrote: ‘According to Liza, the Queen was dismayed that Harry had asked the Archbishop of Canterbury to perform the wedding service in St. George’s Chapel without first requesting permission from the Dean of Windsor.’

‘It sounds quite niche in the circumstances,’ Rebecca said on the latest episode of Palace Confidential. ‘But I do think it gets to the crux of the issue.

‘She was really quite unhappy that Meghan and Harry wanted the Archbishop of Canterbury to marry them at St George’s Chapel at Windsor because actually that was the Dean of Windsor’s territory and it really shouldn’t have happened.’

Although Rebecca acknowledged that Palace Confidential viewers may find this ‘silly’, she explained: ‘When you know about the set up of things, it really was the Dean’s territory.

‘It kind of illustrated how she felt there was a fundamental misunderstanding from the couple about how things worked.

‘It just didn’t sit comfortably with her,’ she added.

As a result, Ms Bedell Smith wrote that Lady Elizabeth believed Harry had ‘blown his relationship with his grandmother’.

Responding to Rebecca, Richard said: ‘You might remember in Harry and Meghan’s Oprah interview that Meghan actually said: “You know what, we got married the night before!”

‘They got the Archbishop of Canterbury round to their backyard, as she called it, and they got married and we know what that was. In reality, that was a rehearsal and they were just going through their vows.

‘That caused awful confusion because the Church actually had to issue a formal statement saying: “We did not marry them the day before i.e. break the law.”‘

Rebecca added: ‘I think the Church suggested it was just basically a blessing ahead of their big day but it did put the Archbishop of Canterbury in a difficult position.

‘He was a big supporter of Harry and Meghan because they had their marital lessons and they had spent time with him discussing their feelings and where they were going.

‘But they totally threw him to the wolves over that,’ she added.

Circling back to Lady Elizabeth’s words, which were published this week, Richard said the ‘most damning of all’ was her apparent suspicion of the former Suits star’s motives in marrying Harry.

‘We hope but don’t quite think she is in love,’ Liza said. ‘We think she engineered it all.’

She also warned: ‘It’s worrying that so many people are questioning whether Meghan is right for Harry. The problem, bless his heart, is that Harry is neither bright nor strong, and she is both’.

‘Meghan is clearly brighter than Harry, but she has to be careful not to overshadow him’, she added.

Liza apparently told Ms Bedell Smith at the time: ‘I don’t trust Meghan an inch. Meghan could turn into nothing but trouble.’

A spokesman for the Duke and Duchess of Sussex declined to comment on the claims made by Sally Bedell Smith.

But a source close to the couple dismissed the sensational claims as ‘just gossip’.
