The first Stephen Lawrence Day is being held to mark 26 years since the teenager was murdered by a racist gang in Eltham, in 1993.
The Prime Minister said she wanted the first Stephen Lawrence Day to inspire youngsters and help ensure his legacy is a “brighter, better future”.
The murder of Stephen Lawrence was a “watershed moment” that forced the country to confront the racism that still exists in society, Theresa May said. She announced the creation of Stephen Lawrence Day last year, on the 25th anniversary of his death.
Meanwhile, 60,000 people have signed a petition to get Stephen Lawrence statue in Trafalgar Square.
