 After a successful visit to Northern Ireland in July 1924 , the Labour government agreed that Albert and Elizabeth could tour East Africa from December 1924 to April 1925 . The Labour government was defeated by the Conservatives in a general election in November ( which Elizabeth described as " marvellous " to her mother ) and the Governor @-@ General of Anglo @-@ Egyptian Sudan , Sir Lee Stack , was assassinated three weeks later . Despite this , the tour went ahead , and they visited Aden , Kenya , Uganda , and Sudan , but Egypt was avoided because of political tensions .
