How did mail in sunday get meghan's letter

I think there may be some confusion here!

Meghan Markle, the Duchess of Sussex, did not receive a letter from Mail-in Sunday. In fact, the controversy surrounding the publication of a private letter from Meghan to her father, Thomas Markle, was a major news story in 2019.

The letter was written by Meghan to her father in August 2018, after he had suffered a heart attack and was unable to attend her wedding to Prince Harry. The letter was intended to be private and was not meant for public consumption.

However, in February 2019, the Mail on Sunday, a British tabloid newspaper, published a copy of the letter without Meghan's permission. The publication sparked widespread outrage and criticism, with many accusing the newspaper of invading Meghan's privacy and breaching the boundaries of a private family matter.

The controversy led to a lawsuit by Meghan against the Mail on Sunday and its parent company, Associated Newspapers, for copyright infringement, misuse of private information, and breach of the Data Protection Act. The lawsuit was settled in October 2021, with the newspaper agreeing to pay Meghan an undisclosed sum and to print a front-page apology.

So, to summarize, Meghan Markle did not receive a letter from Mail-in Sunday, but rather, a private letter from her to her father was published by the Mail on Sunday without her permission, leading to a major controversy and legal action.
