Nanson was elected to parliament at the
1901 state election, winning the
seat of Murchison from the sitting member,
Samuel Mitchell. In November 1901, after only seven months as an MP, he was made
Minister for Lands in the newly formed
Morgans ministry, which lasted for just 32 days. Nanson was elevated to the ministry for a second time in January 1904, as a
minister without portfolio in the
James ministry. He replaced
Hector Rason as
Minister for Works a few months later, but the government fell in August 1904 (after a
vote of no confidence). At the
1904 state election, Nanson had switched seats, defeating
Patrick Stone in the
seat of Greenough. His old seat, Murchison, was lost to the
Labor Party. However, Nanson did not re-contest his seat at the
1905 election, instead travelling to England to study law. He was
called to the bar in 1908, and later that year returned to Australia, reclaiming the seat of Greenough at the
1908 state election. Nanson was elevated to the ministry for a third time in May 1909, as a minister without portfolio in the
Moore ministry. In a reshuffle the following month, he was made
Attorney-General and
Minister for Education. He retained his portfolios when Frank Wilson replaced Newton Moore as premier in September 1910, but the government was defeated at the
1911 election. ==Later life==
