Markle was politically vocal before joining the British royal family.
She backed Hillary Clinton during the 2016 United States presidential election and described Clinton's opponent, Donald Trump, as "misogynistic" and "divisive".
The same year, when the referendum on the United Kingdom's membership of the European Union resulted in 51.9% of voters being in favor of Brexit, Markle expressed her disappointment on Instagram and posted a placard saying: "If EU leave me now, you take away the biggest part of me."
This, as well as her recommendation of Noam Chomsky's book Who Rules the World?,
led Emine Saner of The Guardian to write that Markle would become "the most leftwing member of the royal family".
Members of the royal family are politically neutral by convention, and Dickie Arbiter, former press secretary to Prince Charles, expects the Duchess to follow suit.
Historian Robert Lacey said she was the most "feisty and spiky" person to marry into the royal family since her grandfather-in-law Prince Philip.

After the engagement, Markle's first official public appearance with Prince Harry was at a World AIDS Day walkabout in Nottingham on December 1, 2017.
The Commonwealth Day service at Westminster Abbey on March 12 was the first royal event she attended with the Queen.
The couple made their first visit to Northern Ireland on March 23.
Markle carried out a total of 26 public engagements prior to the wedding.

The Duchess's first official engagement after the wedding came on May 22 when she and her husband celebrated the charity work of his father, Prince Charles.
Her first trip abroad at the request of the British government was to Dublin, Ireland, in July 2018.
The Duchess takes part in her husband's work as youth ambassador to the Commonwealth, which includes overseas tours.
The first such trip was to Australia, Fiji, Tonga and New Zealand in October 2018.
Despite public debate on the future of the monarchy in Australia, the couple were greeted by crowds in Sydney, and the announcement of the Duchess's pregnancy hours after their arrival was received enthusiastically by the public and media.
During their visit to Morocco in February 2019, the Duke and Duchess focused on projects centered on "women's empowerment, girls' education, inclusivity and encouragement of social entrepreneurship".

In 2018, Time magazine included Markle on its list of the 100 Most Influential People in the World, and placed her on its shortlist for Person of the Year.
She was also chosen as one of the most influential women in the United Kingdom by British Vogue magazine.
Her influence was also recognised in both the 2019 and 2020 editions of Powerlist, the 100 most influential Britons of African and Afro-Caribbean descent.

As part of setting up their separate office or 'court' in 2019, the Duke and Duchess created an Instagram social media account, which broke the record for fastest account to reach 1 million followers.
In August 2019, the Duke and Duchess of Sussex were criticized by environmental campaigners for using private jets regularly when taking their personal trips abroad, which would leave more carbon footprint per person compared to commercial planes.
The criticism was in line with the reactions the royal family faced in June 2019, after it was revealed that they "had doubled [their] carbon footprint from business travel".

The Sussexes' discontent with their public roles and unfavourable media scrutiny grew in 2019.
In May 2019, Splash News issued a formal apology to Harry and his wife for sending photographers to their Cotswolds residence, which put their privacy at risk.
The agency also agreed to pay a "substantial" sum of damages and legal costs associated with the case.
At the end of their tour of Southern African countries in September–October 2019, it emerged that the Duchess was suing The Mail on Sunday and MailOnline over the publication of a letter she had sent to her father.
Seventy-two female British MPs sent a public letter of support to the Duchess, condemning the "outdated, colonial undertones" in the press.
