When police in New York shot a young immigrant 41 times in 1999, thousands of people took to the streets to protest.

The US first began sending troops to the UK in 1942 to help in the war effort. It is estimated that at least two million American servicemen passed through the UK during World War Two and tens of thousands of them were black. The African-American GIs stationed in Britain were forced by the American military to abide by the racial segregation laws that applied in the deep south of the US. But that didn't stop relationships developing between British women and the black soldiers, some of whom went on to have children. Babs Gibson-Ward was one those children. She has been speaking to Farhana Haider about the stigma of growing up as mixed raced child in post-war Britain.(Photo: Hoinicote House children, c.1948.
