An election for the leadership of the United Party was held on 21 May 1930 to choose the next leader of the party. The election was won by MP and co-deputy leader of the party George Forbes.
Sir Joseph Ward had been elected leader of the United Party at its inception in 1928. He then led the party at the which resulted in United being able to form a government with support, albeit reluctant, from the Labour Party. By the end of its first year, Ward's government was not living up to expectation. During the election campaign Ward promised that £70 million would be loaned from overseas to fund government programmes, though little was, or could be, borrowed. This left the government without the funds to deal with the rapidly worsening economic recession and growing unemployment. Ward's health declined and his workload was reduced to little more than state administration and chairing cabinet meetings, leaving most of the political management to his two co-deputy leaders, George Forbes and Alfred Ransom. By September 1929 Ward's health worsened after he had a series of heart attacks. He was hospitalised, but improved enough to then travel to Rotorua for treatment and use of its medicinal spa baths. No cabinet meeting were held in the opening months of 1930 but Ward continued to fulfil the administrate affairs of state However, many of his colleagues and family assembled at his bedside on 14 May 1930 where he agreed to resign as leader and Prime Minister.
For the leadership four nominees were voted for in an exhaustive ballot by the United Party caucus which consisted of 25 United MPs, one United MLC (Sir Thomas Sidey) and four independent MPs who caucused with United (Atmore, James Thomas Hogan, William Polson and Charles Wilkinson). Ward was still recuperating in Rotorua and was the only absence. The caucus was held in Wellington in the evening (just after 9pm) on 21 May 1930. In the first ballot Atmore and Veitch polled equal lowest and it was agreed both candidates were eliminated. In the next ballot Forbes beat Ransom to win the leadership. The precise numbers were not revealed but it was reported in the media that the final ballot result was very close.[2]
Ward was telephoned to inform him of the result but he was asleep. He then travelled from Rotorua to Wellington to tender his resignation as Prime Minister to the Governor-General on 28 May. Forbes became Prime Minister but struggled to govern the country in the mounting crisis of the Great Depression. Forbes appointed Ward to his cabinet as a Minister without portfolio, ranked second in the ministry. In 1931 he lost support from the Labour Party who opposed his policy of retrenchment. To continue to govern United had to seek support from the Reform Party. United and Reform contested the election as a coalition and were re-elected, though Reform were the larger of the two. Forbes still remained Prime Minister despite United being the smaller coalition partner. The United–Reform Coalition was defeated at the . Forbes continued as leader of the United Party until 1936 when it was absorbed into the new National Party.
