Title: Andrew Cornwell
Passage: Andrew Stuart Cornwell (born 29 December 1969) is a former Australian politician.  He was a member of the New South Wales Legislative Assembly from the 2011 election until 2014, representing the electorate of Charlestown.  He was elected as a Liberal Party of Australia candidate, and represented that party until 6 August 2014, when he moved to the parliamentary crossbench and sat as an independent after the Independent Commission Against Corruption heard evidence that Cornwell may have breached electoral funding laws.  After earlier announcing that would not contest his seat at the next state election, on 12 August 2014 Cornwell resigned from parliament with immediate effect triggering the 2014 Charlestown by-election.
Title: New South Wales state election, 2011
Passage: Elections to the 55th Parliament of New South Wales were held on Saturday, 26 March 2011.  The 16-year-incumbent Australian Labor Party government led by Premier Kristina Keneally was defeated in a landslide by the Liberal–National Coalition opposition led by Barry O'Farrell.  Labor suffered a two-party swing of 16.4 points, the largest against a sitting government at any level in Australia since World War II.  From 48 seats at dissolution, Labor was knocked down to 20 seats—the worst defeat of a sitting government in New South Wales history, and one of the worst of a state government in Australia since federation.  The Coalition picked up 34 seats to win a strong majority, with 69 seats.  It is only the third time since 1941 that a NSW Labor government has been defeated.
