5. To March Against Racialism. A march through London to oppose racial discrimination, led by Lord Brockway and backed by many organizations, is to be held next Sunday by the Movement for Colonial Freedom. The marches, who will include Young Liberals, students, Young Communists, members of the Connelly Association, Indian and Pakistani organization and others, will meet at Clerkenwell Green at 2 p.m. A deputation led by Lord Brockway and Mr. Stan Newens, M.P. will hand in a letter to the Prime Minister in Downing Street. The march is organized as a counter-demonstration against the march planned by the Immigration Control Association, which demands a total ban on colored immigration and the return of colored immigrants to their countries of origin.
