UK's Johnson hails WWII service of black and Asian troops
"Volunteers from India, Africa and the Caribbean made an immense contribution to victory," he said in a message to the Remember Together campaign, co-organised by the Royal British Legion, a charity that helps veterans.
"I am delighted to remember their sacrifice and celebrate their achievement," he said.
Labour leader Keir Starmer, who has sought to stamp out anti-Semitism in his party, also stressed the commemorations "remember those of every creed and colour".
The party leaders' comments came ahead of the weekend's traditional commemoration ceremonies, for the fallen and veterans of all conflicts since World War I, which will be reduced in scope due to anti-coronavirus restrictions.
The call to give equal weight to the war role of ethnic minorities comes as the Black Lives Matter campaign has sparked angry protests in Britain and the tearing-down of a statue of a slave trader in the southwestern city of Bristol.
