Most of the Southern Rhodesian press predicted that Smith would not last long; one column called him "a momentary man", thrust into the spotlight by the RF's dearth of proven leaders. His only real rival to replace Field had been William Harper, an ardent segregationist who had headed the Dominion Party's Southern Rhodesian branch during the Federal years. Some reporters predicted Welensky's imminent introduction to Southern Rhodesian politics at the head of an RF–UFP coalition government, but Welensky showed little interest in this idea, saying he would be unable to manoeuvre in an RF-dominated House. The RF's replacement of Field with Smith drew criticism from the British Labour leader Harold Wilson, who called it "brutal", while John Johnston, the British High Commissioner in Salisbury, indicated his disapproval by refusing to meet Smith for two weeks after he took office. The ZAPU leader Joshua Nkomo branded the new Smith Cabinet "a suicide squad ... interested not in the welfare of all the people but only in their own", and predicted that the RF would "eventually destroy themselves". Asserting that a lasting "place for the white man" in Southern Rhodesia would benefit all of the country's people, the new Prime Minister said the government should be based "on merit, not on colour or nationalism", and insisted that there would be "no African nationalist government here in my lifetime".
