The mother of the murdered teenager Stephen Lawrence says that twenty years after his death his siblings are affected "more than anyone could know".
Doreen Lawrence said that earlier this year the charity set up in the memory of Stephen received a racist threat targetted at her other son Stuart.
"They do the best they can and, like me, they don't really dwell that much, but you know in their moments how depressing it is for them," Doreen said.
A memorial service has been held to mark the 20th anniversary of the racist murder of Stephen Lawrence.
Twenty years after Stephen Lawrence's death, an exclusive poll reveals perceptions of attitudes towards race in the Metropolitan Police.
