Porter stood for the Presidency of the NUS as the candidate of the Organised Independents faction, but is a member of the Labour Party. He was subsequently elected with a 65% majority and took office in June 2010, which he would hold for the period of one year. Taking control of the Union, Porter put forward his views that he was in favour of lowering the voting age to sixteen, and stated he would lead a national demonstration against the government's planned rise in tuition fees before any vote in Parliament on the issue. On taking up the NUS Presidency, Porter was profiled in The Observer where he re-stated his opposition to any increase in tuition fees as well as the need for a new approach to campaigning that includes both formal lobbying as well as active campaigning. Backing a graduate tax as an alternative method of financing higher education, Porter stated that funding would need to be fair and progressive for students to support it. A keynote speech on the future of higher education warned of the implications of a funding crisis. He has also been vocal on the issue of graduate employment with significant national coverage. In November 2010, Porter appeared on the Daily Politicstelevision show, arguing against the raising of students' tuition fees. In response to the review of Higher Education Funding and Student Finance chaired by Lord Browne, the National Union of Students organised a National Demonstration in London jointly with the University and College Union. 50,000 protestors took part in the protest, at the end of which Porter addressed a rally outside Tate Britain. During the immediate aftermath of this demonstration on 10 November 2010, by over 50,000 people, Porter condemned the occupation of the Conservative Party's headquarters, referring to it as "violence by a tiny minority". In January 2011 at an anti-cuts march and rally in Manchester, Porter was escorted away by police from a small section of the crowd of student protesters who were heckling and shouting "you're a Tory too" – a chant commonly used against Liberal Democrats during the student fees protests. There was also a report claiming their photographer had overheard anti-semitic abuse, despite Porter not being Jewish. In February 2011 Porter said he had decided not to seek re-election for Presidency of the NUS, stating he felt the Union would benefit from new leadership.
