Election to parliament On 18 March 2011,
Nine News Queensland Spencer Jolly reported that the LNP's organisational wing was engineering a plan to make Newman the leader of the LNP. According to Jolly, party president
Bruce McIver was trying to arrange for
Bruce Flegg, the former leader of the Queensland Liberals and the MP for
Moggill, the only safe LNP seat in Brisbane at the time, to resign and hand his seat to Newman. Under this plan, once Newman was safely in the legislature, he would have challenged Opposition Leader
John-Paul Langbroek—who, like Newman, is from the Liberal side of the LNP merger—for the leadership of the LNP. Newman subsequently acknowledged he had been approached about moving up to state politics. Although he did not rule out running in the next state election he stated that, for the time being, he was committed to serving out his term as lord mayor and running for re-election in 2012. However, on 22 March, Newman announced that he was seeking the LNP preselection for the west Brisbane seat of
Ashgrove, held by Labor's
Kate Jones, in the election due for 2012. If he won preselection, Newman said, he would then make a bid for the LNP leadership. According to
ABC News, the LNP's organisational wing wanted Newman to run for a state seat and the leadership when polls showed he was the only non-Labor politician who matched Premier
Anna Bligh's popularity during the
2010–11 Queensland floods. Jones held Ashgrove with a margin of 7.1 points, making it a "fairly safe" Labor seat, on paper. However, according to
Australian Broadcasting Corporation elections analyst
Antony Green, Newman carried The Gap ward, which contains the bulk of Ashgrove (Brisbane City Council wards are almost as large as state electorates), with 56 per cent of the
two-party vote in 2004 and almost 70 per cent in 2008. According to Green, if Newman repeated his past performance in The Gap, he would be able to take Ashgrove off Labor. Within hours of Newman's announcement, Langbroek and deputy leader
Lawrence Springborg both resigned their posts. Langbroek had been under growing pressure from the LNP's organisational wing to stand down after Labor's polling numbers rebounded in the wake of the floods. However, as late as a day before Newman's announcement, Langbroek insisted he would not do so. On 2 April 2011, Newman was elected as the leader of the LNP. The next day he won the LNP preselection for Ashgrove, unopposed. Normal practice in a Westminster system would have called for an LNP member of parliament from a safe seat to resign so that Newman could enter parliament via a by-election. However, it became apparent that a by-election could not be arranged. To solve this problem, former state Nationals leader Jeff Seeney, who had been elected deputy leader of the LNP, was named as the party's interim parliamentary leader—and hence
Leader of the Opposition—while Newman led the LNP election team from outside the legislature. Seeney agreed to cede the post of parliamentary leader to Newman should Newman win election to the legislature. Newman's ascent to the role of leader outside of Parliament led Bligh to briefly consider breaking her previous vow to let the legislature run full-term. She had promised to focus exclusively on recovery in 2011, but was concerned that the LNP's leadership situation could make the co-operation necessary for the recovery effort impossible. Bligh also accused Newman of "abandoning" the lord mayor's post, saying that Newman should not have "cut and run" while the recovery effort was still underway. Soon after Newman became leader of the LNP, Labor state treasurer
Andrew Fraser used parliamentary privilege to claim he had received information from within the LNP that Flegg had been given an inducement to resign and allow Newman to run for his seat in a by-election. On 18 July 2011, the
Crime and Misconduct Commission announced that the investigation found no evidence to support Fraser's allegations and all parties were cleared. Billionaire and LNP benefactor
Clive Palmer said the "CMC [was] colluding with the government" while the LNP accused Fraser of "knowing too much about the investigation". Newman made it clear that when he took over the LNP leadership, all policies previously announced would be scrapped and essentially become "null and void" with new policy announcements to be made. In an attempt to win voter support in regional Queensland, Newman's first official LNP policy announcement was that he would not support
daylight saving in Queensland or
South East Queensland, even though as Brisbane's Lord Mayor he had been a vocal advocate for daylight saving. Newman stated his support for
same-sex marriage. The LNP, however, stated prior to the 2012 election that if they win government they may move to repeal such laws. On 30 May 2021, Newman was made one of the LNP's trustees, a party elder position that is involved in finances and has a seat on the state executive. It is understood that the acting LNP President, Cynthia Hardy, approached Newman about the role, to which he was then elected in a vote of state executive.
Election victory On 25 January 2012, Bligh announced that a state election would be held in Queensland on 24 March, but that she would not formally ask the Governor to dissolve parliament until 19 February. For Newman to unseat Bligh as premier, he needed not only to win Ashgrove, but also lead the LNP to at least an 11-seat gain. However, the LNP were unbackable favourites to win the election; as mentioned above they had been leading in opinion polling for all but a few months since July 2011. On 15 March 2012, Bligh referred to the Crime and Misconduct Commission material concerning an office in a building owned by interests associated with Newman's family. Despite allegations of inappropriate dealings for personal benefit, a week before the election the CMC finalised its assessment that there was no evidence of official misconduct by Newman while he was Lord Mayor of Brisbane. Consequently, no further investigation was warranted nor would be conducted by the CMC concerning Newman. In the election, Newman led the LNP to a comprehensive victory. The LNP won 78 seats against only seven for Labor, taking 44 seats on a swing of 14.5 points. That was largely because Brisbane, Labor's power base for more than 20 years, swung over dramatically to support Newman. The LNP won an unprecedented 37 seats in Brisbane, in many cases on swings of 10 points or more. By comparison, it had gone into the election holding only six of the capital's 40 seats; Labor had held power mostly on the strength of winning at least 30 seats there in every election since 1989. It was easily the worst defeat a sitting government has ever suffered in Queensland, and one of the most lopsided election results ever recorded at the state level in Australia. Newman himself won a convincing victory in Ashgrove, taking 51 per cent of the primary vote and 54 per cent of the
two-party vote on a swing of 13.8 points—almost double the swing needed. Newman formally claimed victory at 8:45 pm Queensland time, saying he had received a mandate to make Queensland "a can-do place once more." The LNP had run on the slogan "Can Do Queensland" (stylised as "CanDoQLD")—derived from his mayoral campaign slogan, "Can Do Campbell". ==Premier==
