Prince Harry's wife, Megan, has accused Buckingham Palace of perpetuating falsehoods about her and her husband, saying the royal couple would not be silent in telling their story.

Her comments were released as part of the latest teaser ahead of the couple's much anticipated interview with American talk show host Oprah Winfrey Do to be broadcast on US television this Sunday.

The clip dropped just hours after Buckingham Palace said it was very concerned about reports in Britain's Times newspaper alleging that Megan had bullied assistance.

Working for her two years ago, Harry and Meghan issued a statement denying that she had bullied anyone.

This latest Oprah interview clip shows Megan being asked quote, How do you feel about the palace hearing you speak your truth today?

Referring to the royal family as the firm, she replies by saying quote.

I don't know how they could expect that after all of this time.

We would still just be silent if there is an active role that the firm is playing in perpetuating falsehoods about us.

Michelle Talbot is the senior Royals editor for People magazine.

I think that after this interview airs, many people are going to wonder why the royal family couldn't make this work.

The monarchy failed.

There was a golden opportunity to modernize with this couple and, uh and it didn't happen.

They lost.

They lost what could have been.

Oprah's interview was recorded before The Times newspaper ran a report, citing unnamed sources saying an aide to Harry and Megan had raised a complaint in October 2018 alleging that Megan had reduced some assistance to tears and treated others so badly that they quit.

The paper said Harry had urged the aide, who has now left their staff to drop the complaint, and it never progressed.

Reuters could not independently verify the report.
