New racism allegations have once again confronted Buckingham Palace, with documentation to back up the said claims.

The said allegations of racism involve Queen Elizabeth II's top courtier, who was said to ban "colored immigrants or foreigners" from serving in clerical roles in the royal household until at least the late 1960s, according to a USA Today report.

Documents from 1968 allegedly reveal how the Queen's chief financial manager informed civil servants that it was not the practice to appoint colored immigrants or foreigners to clerical roles in the royal household, although they were permitted to work as domestic servants.

The papers were discovered at the National Archives as part of The Guardian's ongoing investigation into the royal family's use of the parliamentary procedure, according to The Guardian report.

The said procedure was also known as the Queen's consent, which was reportedly used to secretly influence the content of British laws.

However, it was not clear when the practice ended. Buckingham Palace had also refused to answer questions about the ban on colored immigrants and when it was put out of practice.

The top positions advising the monarch were mostly of white descent, upper-class or aristocratic males. Many were Oxbridge grads and/or served in high-ranking positions in the military.

Royal Exemptions

Meanwhile, the Queen has remained personally exempted from equality laws for more than four decades after government ministers sought to instate a law that would make it illegal to refuse to employ an individual on the grounds of their race or ethnicity.

The exemption has made it impossible for people from ethnic minorities working for the royal household to complain to courts if they believe they had been discriminated against, according to an Aljazeera report.

Buckingham Palace had said that it has a separate process for hearing complaints regarding discrimination claims. However, it did not add any further details.

The official documents show that government officials in the 1970s coordinated with Queen Elizabeth II's advisers on the wording of the laws.

Racism Issues

In March, Buckingham Palace had allegations of racism raised by Prince Harry and Meghan Markle after their interview with Oprah Winfrey.

Buckingham Palace at the time said that they would address the matter privately, according to a Wall Street Journal report.

Markle had been candid during the Winfrey interview, saying that she was feeling suicidal while working in the palace.

In addition, she noted that a member of the royal family had echoed concerns about how dark her unborn child's skin would be.

Buckingham Palace released a statement, saying that they will be addressed by the family privately and that they will be much-loved family members.

The racism claims have been one of the issues pushing the House of Windsor to change toward a new generation.

Prime Minister Boris Johnson had declined to be part of the issue, while Prince Charles had remained mum on the matter.

He was seen on his first public outing since the interview, visiting a vaccination center to help encourage vaccinations among people of color.

He was asked about his thoughts on the matter, wherein he responded by walking away.

Meanwhile, the Queen said that she was unaware of the problems Markle had experienced.
