Abbott led the Coalition at the 2010 election, which resulted in a hung parliament. Following negotiations, Labor formed a Government, with the support of one Green MP and three Independent MPs. Abbott was re-elected as Liberal Leader unopposed. Abbott went on to lead the Coalition to victory in the 2013 election and was sworn in as the 28th Prime Minister of Australia on 18 September 2013. The Abbott Government aimed to rein in a budget deficit that reached A$48.5 billion by June 2014. It concluded free trade agreements with China, Japan and South Korea. It removed the Rudd-Gillard era Resource Super Profits Tax and carbon pricing. It established the National Commission of Audit to advise on restoring the Budget to surplus; instituted the Royal Commission into trade union governance and corruption; founded the Medical Research Future Fund; and produced White Papers on Developing Northern Australia and the Agricultural Competitiveness.
