First steps, under Field Field's failure to secure independence concurrently with the end of the Federation caused his Cabinet's support for him to waver during late 1963 and early 1964.{{Harvnb The RF united behind Field after Sandys wrote him a terse letter warning him of the likely Commonwealth reaction to a declaration of independence, but the Prime Minister then lost his party's confidence by failing to pursue a possible route to at least
de facto independence devised by
Desmond Lardner-Burke, a lawyer and RF MP for
Gwelo. During March 1964, the Legislative Assembly in Salisbury considered and passed Lardner-Burke's motion that the Governor, Sir
Humphrey Gibbs, should submit a petition to the Queen requesting alteration of Section 111 of the 1961 constitution so that the
Royal Assent described therein would be exercised at the request of the Southern Rhodesian government rather than that of its British counterpart. This would both remove the possibility of British legislative interference and pave the way for an attempted assumption of independence by
Order in Council.{{#tag:ref|The Lardner-Burke bill proposed that a two-thirds majority in the Legislative Assembly would prompt automatic consent for alterations from the Governor, who would then sign them into law on behalf of the Queen.{{Harvnb The RF's intention was partly to test whether or not the British would attempt to block this bill after Gibbs had granted Royal Assent to it,{{Harvnb

Roy Welensky, who held the Federal premiership from 1956 to dissolution in 1963, was also born in Southern Rhodesia. Before Smith, Southern Rhodesia had had seven Prime Ministers, three of whom (including Field) had been born in Britain. The country's first two Prime Ministers,
Charles Coghlan (1923–27) and
Howard Moffat (1927–33), were respectively born in South Africa and
Bechuanaland,{{Harvnb Salisbury's blunt refusal to be part of the Wind of Change caused the
Southern Rhodesian military's traditional British and American suppliers to impose an informal embargo, and prompted Whitehall and Washington to stop sending Southern Rhodesia financial aid around the same time. In June 1964, Douglas-Home informed Smith that Southern Rhodesia would not be represented at the year's
Commonwealth Prime Ministers' Conference, despite Salisbury's record of attendance going back to 1932, because of a change in policy to only include representatives from fully independent states. This decision, taken by Britain to preempt the possibility of open confrontation with Asian and black African leaders at the conference, deeply insulted Smith.{{Harvnb met Smith in London in September 1964.|alt=A photograph of Sir Alec Douglas-Home At
10 Downing Street in early September 1964, impasse developed between Douglas-Home and Smith over the best way to measure black public opinion in Southern Rhodesia. A key plank of Britain's Southern Rhodesia policy was that the terms for independence had to be "acceptable to the people of the country as a whole"—agreeing to this, Smith suggested that white and urban black opinion could be gauged through a general referendum of registered voters, and that rural black views could be obtained at a national
indaba (tribal conference) of chiefs and headmen. Douglas-Home told Smith that although this proposal satisfied him personally, he could not accept it as he did not believe the Commonwealth, the United Nations or the Labour Party would also do so. He stressed that such a move towards accommodation with Smith might hurt the Conservatives' chances in the British general election the next month, and suggested that it might be in Smith's best interests to wait until after the election to continue negotiations. Smith accepted this argument. Douglas-Home assured Smith that a Conservative government would settle with him and grant independence within a year.{{Harvnb Attempting to form a viable white opposition to the Rhodesian Front, the UFP resurrected itself around Welensky, renamed itself the Rhodesia Party, and entered the Arundel and Avondale by-elections that had been called for 1 October 1964. Perturbed by the prospect of having to face the political heavyweight Welensky in parliament at the head of the opposition, the RF poured huge resources into winning both of these former UFP safe seats, and fielded
Clifford Dupont, Smith's deputy, against Welensky in Arundel.{{#tag:ref|During the bitterly fought campaign,{{Harvnb

general election on 15 October 1964, and formed a government the next day. Both Labour and the Conservatives told Smith that a positive result at the
indaba would not be recognised by Britain as representative of the people, and the Conservatives turned down Salisbury's invitation to send observers. Smith pressed on, telling parliament that he would ask the tribal chiefs and headmen "to consult their people in the traditional manner", then hold the
indaba as planned.{{Harvnb While the chiefs conferred, Northern Rhodesia became independent Zambia on 24 October 1964, emulating Nyasaland, which had achieved statehood as Malawi three months earlier. Reasoning that it was no longer necessary to refer to itself as "Southern" in the absence of a northern counterpart, Southern Rhodesia began calling itself simply Rhodesia.{{#tag:ref|Salisbury passed legislation to shorten the name, but Britain ruled this
ultra vires as the laws naming the country were British acts passed at Westminster. Salisbury went on using the shortened name in an official manner anyway,{{Harvnb When the
indaba ended on 26 October, the chiefs and headmen returned a unanimous decision to support the government's stand for independence under the 1961 constitution, attesting in their report that "people who live far away do not understand the problems of our country".{{Harvnb
Stalemate develops between Smith and Wilson Smith wrote to Wilson the day after the referendum, asking him to send Bottomley to Salisbury for talks. Wilson replied that Smith should instead come to London. The British and Rhodesians exchanged often confrontational letters for the next few months. Alluding to the British financial aid pledged to Salisbury as part of the Federal dissolution arrangements, Wilson's High Commissioner in Salisbury,
J B Johnston, wrote to the Rhodesian Cabinet Secretary
Gerald B. Clarke on 23 December that "talk of a unilateral declaration of independence is bound to throw a shadow of uncertainty on the future financial relations between the two governments".{{Harvnb , where Wilson received Smith in January 1965|alt=A wide shot of Downing Street The two premiers were brought together in person in late January 1965, when Smith travelled to London for Sir
Winston Churchill's funeral. Following an episode concerning Smith's non-invitation to a luncheon at
Buckingham Palace after the funeral—noticing the Rhodesian's absence, the Queen sent a royal
equerry to Smith's hotel to retrieve him, reportedly causing Wilson much irritation—the two prime ministers inconclusively debated at 10 Downing Street. They differed on most matters, but agreed on a visit to Rhodesia the next month by Bottomley and the Lord Chancellor,
Lord Gardiner, to gauge public opinion and meet political and commercial figures.{{Harvnb The RF called a new general election for
May 1965 and, campaigning on an
election promise of independence, won all 50 "A"-roll seats (the voters for which were mostly white).{{#tag:ref|The electoral system devised in the 1961 constitution replaced the common voters' roll with two rolls, the "A" roll and the "B" roll, the latter of which had lower qualifications intended to make it easier for prospective voters to enter the political system. There were 50 "A"-roll constituencies and 15 larger "B"-roll districts, with a complicated mechanism of "cross-voting" allowing "B"-roll voters to slightly influence "A"-roll elections and
vice versa. This system was theoretically non-racial, but in practice the "A" roll was largely white and the "B" roll was almost all black.{{Harvnb
Final steps to UDI {{quote box|align=right|width=40%|{{dialogue Amid renewed rumours of an impending Rhodesian UDI, Smith travelled to meet Wilson in London at the start of October 1965, telling the press that he intended to resolve the independence issue once and for all.{{Harvnb During these discussions, Smith referred to the last resort of a UDI on many occasions, though he said he hoped to find another way out of the quandary. He offered to increase black legislative representation by expanding the electorate along the lines of "one taxpayer, one vote"—which would enfranchise about half a million, but still leave most of the nation voteless—in return for a grant of independence.{{Harvnb Stalemate drew closer as the Rhodesian Cabinet resolved that since Wilson had ruled out maintenance of the
status quo, its only remaining options were to trust in the Royal Commission or declare independence.{{Harvnb Amid frantic efforts by Beadle and others on both sides to revive the Royal Commission, the Rhodesian government had Gibbs announce a
state of emergency the same day on the grounds that black Rhodesian insurgents were reportedly entering the country. Smith denied that this foreshadowed a declaration of independence,{{Harvnb ==Draft, adoption and signing==
