Royal uncle Prince Harry and future royal aunt Meghan Markle stepped out in London on Monday — just hours after Kate Middleton and Prince William welcomed a baby boy. A few miles away from St. Mary’s Hospital — where Kate gave birth to her third child — the couple attended a memorial service to commemorate the anniversary of the murder of Stephen Lawrence — a black British man who was killed in a racially charged attack 25 years ago at the age of 18 — and to celebrate his life and legacy. This year marks 25 years since Stephen Lawrence was killed, and 20 years since The Stephen Lawrence Charitable Trust was founded. Established by Baroness Lawrence in 1998 in memory of her son, for the past 20 years the Stephen Lawrence Charitable Trust has campaigned for fairness, justice and equality for all.

During the service, the prince read a message of support on behalf of Prince Charles. Can’t get enough of PEOPLE’s Royals coverage?
