on Tax & Revenue, a role in which he worked on improving access to 'light touch' tax returns for individuals with simple tax affairs. Following this he was appointed chair of the House Standing Committee on Economics, where he instigated an inquiry into home ownership and opportunities for tax reform. Following Malcolm Turnbull's ascension to Prime Minister John Alexander was appointed chair of the newly formed House Standing Committee on Infrastructure, Transport & Cities, where he commenced an inquiry into transport connectivity, regional development, high speed rail and the use of value capture as an innovative funding mechanism. Alexander also served as chair of the Coalition Policy Committees on Infrastructure & Regional Development, and on Tourism, of the Sydney Airport Community Forum, and of the Australia-East Asia Parliamentary Network. As a strong proponent of high-speed rail linking Australia's eastern seaboard, Alexander delivered the keynote speech at a high-speed rail conference at University of Melbourne in February 2014, highlighting the resultant opportunities for regional development and reduction in traffic congestion in major cities. Alexander was not challenged in Liberal preselection in 2016. In the 2016 election, he was re-elected as member for Bennelong, earning a small swing toward him despite the state - and the nation - swinging toward Labor. Alexander's hold on Bennelong was largely attributed to his high personal vote in the electorate. During the Australian parliamentary eligibility crisis, on 6 November 2017, it was reported that Alexander might also be a British citizen and so had never been eligible for election to the Parliament. On 11 November 2017, Alexander resigned from parliament after conceding that he was likely a dual citizen, necessitating a by-election in Bennelong. He renounced his UK citizenship and stood as the Liberal Party candidate at the by-election, held on 16 December 2017. During his campaigning, a YouTube video of Alexander in the 1990s, uploaded in 2011, was resurfaced in the media. The video displays Alexander telling racist jokes at an end of year party with film crew from the 1990s TV show Gladiators. Once the video was shared with the ABC, Alexander immediately released a written statement that described how the jokes were "completely unacceptable". Alexander elaborated: "There is no place for jokes about violence against women. Again, I apologise unreservedly". Then Prime Minister, Malcolm Turnbull, praised Alexander's claims, saying his apology was "a measure of the man [...] Not all disrespect of women
