Prince Harry made a firm stance earlier this week against those harassing his actress-girlfriend, Meghan Markle, but that hasn’t stopped the royal from fulfilling his official obligations. On Thursday, he attended the Field of Remembrance Service at Westminster Abbey in London alongside his grandfather, Prince Philip.

Harry wore the symbolic red poppy pin as he participated in the ceremony honoring fallen soldiers.

The event marks Harry’s first public appearance since releasing a rare statement on Tuesday, slamming the “outright sexism and racism of social media trolls and web article comments” against the Suits star.

His statement also confirmed his previously rumored relationship, explicitly calling Markle his “girlfriend.”

Also on Thursday, the Palace released the official itinerary for Harry’s two-week royal tour of the Caribbean, which will run from Nov. 20 through Dec. 4.

The prince will visit seven different countries over that span of time and celebrate the 35th Anniversary of Independence in Antigua and Barbuda and the 50th Anniversary of Independence in Barbados and Guyana.
