Question: Which Austrailian politician served as the Premier of New South Wales, Walt Secord or Kristina Keneally?
Context: Walter "Walt" Secord (born 25 December 1964) is a Canadian-born Australian politician.  He has been an Australian Labor Party member of the New South Wales Legislative Council since May 2011, when he was elected to fill the vacancy left by the retirement of Eddie Obeid.  Secord was previously the Chief of Staff to former NSW Premier, Kristina Keneally. The Premier of New South Wales is the head of government in the state of New South Wales, Australia.  The Government of New South Wales follows the Westminster system, with a Parliament of New South Wales acting as the legislature.  The Premier is appointed by the Governor of New South Wales, and by modern convention holds office by virtue of his or her ability to command the support of a majority of members of the lower house of Parliament, the Legislative Assembly. Carmel Mary Tebbutt (born 22 January 1964) is an Australian former politician.  She was the Australian Labor Party Member for the former seat of Marrickville in the New South Wales Legislative Assembly until the 2015 election and was Deputy Premier of New South Wales from 2008 to 2011.  She was also Minister for Health in the Keneally Government.  She is the first woman to hold the position of Deputy Premier of New South Wales. Steven James Robert "Steve" Whan ( ) (born 11 February 1964), an Australian politician, was a member of the New South Wales Legislative Council from 2011 to 2015.  Whan represented the electoral district of Monaro in the New South Wales Legislative Assembly for the Australian Labor Party from 2003 until his defeat at the 2011 state election.  Whan served as Minister of Emergency Services, Minister for Small Business and Minister for Rural Affairs in the Rees and Keneally ministries from 2009 to 2011. Heffron is an electoral district of the Legislative Assembly in the Australian state of New South Wales.  It is named after Robert Heffron, a former Labor premier of New South Wales.  It is a safe Labor seat, and was recently represented by Kristina Keneally of the Australian Labor Party and she like Heffron had also served as Premier.  On 23 June 2012, Keneally announced that she would be resigning on 29 June 2012 to start her new career as CEO of Basketball Australia, prompting an August Heffron by-election.  At the 2011 election, Keneally suffered a swing of over 16 percent, more than halving her majority from 23 percent to seven percent.  However, at the by-election, the seat reverted to form as Labor candidate Ron Hoenig won with 70 percent of the two-candidate preferred vote. The Keneally ministry is the 92nd ministry of the Government of New South Wales, and was led by the 42nd (and first female) Premier Kristina Keneally. Tanya Rachelle Gadiel, "née" Barber (born 21 November 1972), a former Australian politician, was a member of the New South Wales Legislative Assembly between 2003–2011, representing the electorate of Parramatta for the Australian Labor Party.  During her term in Parliament, Gadiel was Deputy Speaker of the New South Wales Legislative Assembly in the Kristina Keneally Labor Government.  On 8 December 2010, Gadiel announced that she will not contest the 2011 state election. Kristina Kerscher Keneally (born 19 December 1968) is a journalist and former Australian politician who served as the 42nd Premier of New South Wales.  She was elected leader of the Australian Labor Party in New South Wales and thus Premier in 2009, but went on to lose government to the Liberal/National Coalition at the March 2011 state election.  On 29 June 2012, Keneally resigned from parliament. 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. A by-election occurred for the New South Wales Legislative Assembly seat of Heffron on Saturday 25 August 2012.  This was triggered by the resignation of former Premier of New South Wales and state Labor MP Kristina Keneally which she announced on 23 June 2012.  Labor easily retained the seat with an increased margin.  Ron Hoenig received a 60 percent primary and 70 percent two-candidate preferred vote.
Answer: Kristina Keneally
