THE DUCHESS of Sussex has received a backlash for using her royal title in a letter to US politicians.

Meghan Markle sent the letter to the Speaker of the US House of Representatives Nancy Pelosi and Charles Schumer, the Majority Leader of the US Senate.

The letter, which was calling paid parental leave, was signed with her official royal title.

In the plea, Meghan also shared her personal experiences of managing her working life with her responsibilities raising children.

She admitted she and husband Prince Harry had felt “overwhelmed” by the birth of their second child Lilibet in June this year.

The letter was signed off from “the office of the Duke and Duchess of Sussex”.

The public are divided on the decision to include the royal titles, having stepped back from senior royal duties in 2020.

Since the decision to distance themselves from the royal family, the couple are no longer permitted to use HRH titles.

One Twitter user accused Meghan of “using her title in America to make a political point”.

Another added: “She is not allowed to use it to earn money or make political statements.”

Earlier this week, Meghan’s father Thomas Markle said he would love to see his grandchildren, but feared being branded a “stalker” if he made attempts to visit them.

Speaking on ITV’s Good Morning Britain, he said he was “very concerned” he would never get to meet Prince Harry and Meghan Markle’s children.

He went on to blame Prince Harry for his relationship issues with his daughter, before slamming the Duke for “abandoning" the Queen, the army and the British people.

"All he does now is ride a bicycle around the neighbourhood,” he said. “I don't know if it's much of a life for him either. It doesn't make sense."

Commenting on the Duke’s upcoming book release, Thomas said: “Everything they’re doing is for money.

“To do that to your grandmother, who is 95 years old, is shameful.”
