I've gone back to check - the witness statements from both Thomas Markle and the MoS/Associated Newspapers say that TM did not ask for and did not receive payment for showing them Meghan’s letter.
A very short extract from his witness statement is as follows:
“Although I was approached by other journalists for comment after the article in People magazine was published, I decided to reach out to Caroline Graham of the Mail On Sunday to say that I wanted to get the truth out there.
I never asked for and I never received any payment for the article.
It was important to me in setting the record straight about me and about the tone and content of the letter that Caroline should not just describe what Meg had written but that she should actually quote from and reproduce parts of the letter.
If the public didn’t see the letter and read what it said in its own words, I did not think anyone would believe me.
The Mail On Sunday respected my wish to publish extracts from the letter as it was telling my story and it was up to me to say which parts of the letter needed to be published for me to tell that story.
I was therefore shown all of the extracts and I approved publication of those extracts. I could have said no if they had wanted to publish parts of the letter which I didn’t want published.
The choice was mine. I did not want the whole of the letter to be published. The reason for that was because I thought the letter as a whole made Meg look terrible.
I do not want to attack or hurt her. I just wanted to defend myself by countering the impression given of me and of the letters between Meg and me by the People article, and I didn’t think it was necessary to publish the whole letter to do that – but it was necessary to publish the extracts that were published.”
