1899 to his death in 1913. From 1909 until 1910 he was senior whip of the Liberal Party.
New Liberal Party Laurenson was the nominal leader or chairman of the
New Liberal Party in 1905 though
Tommy Taylor was the dominant figure. Like Taylor, Laurenson favoured federation with Australia. Laurenson was one of the few who stood as a New Liberal in the election and retained his seat. Most, including Taylor were defeated.
Cabinet Minister On 22 March 1912 he stood in
a leadership election against
Thomas Mackenzie to decide the successor to Sir
Joseph Ward as leader of the Liberal Party, but lost (9 votes to 22). He was subsequently the Deputy Prime Minister and Minister of Labour, Customs and Marine in Mackenzie's cabinet. In July the
Liberal government was defeated, after the defection of some Liberal members like
John A. Millar to Reform. ==Local politics==
