He revealed: "I have been frozen out and I can’t stay silent.
"I have made dozens of attempts to reach my daughter via text and letters, but she and Harry have put up a wall of silence.
"They have done what they once told me not to do – they are believing everything negative that has been written about me.
"So I am reaching out to them, once again, to try to correct the lies and get the truth out there.
"Everyone says, why don’t I just shut the f*** up? That Meghan can’t speak to me because I’ll give away secrets. But that’s bull****.

Thomas mocks claims that he staged a heart attack after he could not attend the Royal Wedding by producing a stack of private medical bills and a hospital discharge letter.

However, despite reaching out to his daughter since she became The Duchess Of Sussex he has been met with a wall of silence.
He added: "I’ve pleaded with her to pick up the phone. I wrote her a two-page letter and sent it by certified mail via her representative in Los Angeles. I asked her why she was believing all the lies.
" I also pointed out the Royals haven’t always been perfectly behaved. I wrote that I’ve never played pool naked, nor have I dressed up as a Nazi a reference to Harry’s infamous pictures in Las Vegas in 2012 and the time that he wore a crude imitation of a Nazi uniform, including a swastika armband, in 2005.

"All I want to do is make you proud… and I promise, no matter what, I’ll do it. Thank you for everything daddy. I love you with all of my heart now and forever. Love Bean’ – a reference to his childhood nickname for her."

When asked if he will re-unite with his daughter he reveals that he hopes that it could still happen one day
He adds: "Maybe. Some day.
"Their treatment of me is harsh, hurtful and unforgiving. I’m being punished for things I didn’t say.
"I’m trolled on the internet by one guy who sits in his mother’s basement spewing lies about me. Twitter is the worst but I can’t avoid it.
