[b]Charles Wilson Tuckey [/b]MP (born 10 July 1935), Australian politician, has been a Liberal member of the Australian House of Representatives since October 1980, representing the Division of O'Connor, Western Australia.

He was born in Perth, Western Australia, and was a businessman and hotelier before entering politics. Tuckey is the oldest member of the House, aged 74 as at December 2009.

In the federal Parliament he was a member of the Opposition Shadow Ministry (1984–89 and 93–96). He was Deputy Manager of Opposition Business in the House (1988–89 and 1993–94). He was Minister for Forestry and Conservation and Minister Assisting the Prime Minister (1998–2001) and Minister for Regional Services, Territories and Local Government (2002–2003).

Tuckey is one of the most controversial figures in Australian federal politics. In 1967, while a publican in Carnarvon, he was convicted of assault after striking an Aboriginal man with a length of steel cable. It was alleged that the man was being pinned to the ground at the time.

Tuckey's demise as a minister came in August 2003 when it was revealed that he had written to Patrick Conlon, who was Police Minister in South Australia, on ministerial letterhead, asking Conlon to "review" his son's conviction on a traffic charge.
Prime Minister Howard said that Tuckey's actions were foolish but refused to dismiss him. Tuckey resigned as a minister shortly afterwards to return to the backbench.

In 2005 when the Australian parliament voted to pass a motion asking Singaporean authorities that Van Tuong Nguyen not be executed for drug smuggling, Tuckey was the only member of parliament not to support it.

Tuckey is often quoted in the media as supporting free markets and less government intervention in the economy, he also well known for criticising the National Party on a number of issues.
He has been the most outspoken critic of AWB in Federal Parliament and has led the push for it to be stripped of its export monopoly for wheat.
Tuckey labelled National Party politicians who continue to support the single desk system as "drongos".
He also labelled National Party senator Barnaby Joyce a "lightweight" for arguing in favour of foreign ownership restrictions to be placed upon Medibank Private after privatisation.

In 1989 Tuckey was one of the leaders of the plot to depose John Howard as Liberal Party leader and replace him with Andrew Peacock. After the success of the plot, Tuckey boasted about it on television, privately infuriating Howard.

In August 2007, Tuckey sent a fax to John Howard and several Liberal MPs suggesting the Prime Minister relinquish the leadership.

In January 2008 Tuckey was labelled as an "extreme racist" by Queensland Aboriginal activist Sam Watson, after criticising the decision that traditional dancers from the Aboriginal tribe which historically reside in the area of Parliament House would appear as part of the opening of Federal Parliament. Mr Watson concluded his remarks with the statement that "Mr Tuckey and his extremist racist views really do belong to another generation."

On 13 February 2008, Tuckey walked out during the opening of the 42nd Australian Federal Parliament immediately after prayers, and pointedly before the Prime Minister Kevin Rudd made a motion of apology to the Stolen Generation.
Mr Tuckey was one of five Coalition MPs not present in the chamber, thereby boycotting the motion. On the steps of parliament, Tuckey was sarcastic about what the apology would achieve for indigenous people.

In May, 2008, Tuckey was expelled from the house for 24-hours after breaching standards.

On 24 September 2008, Tuckey was again expelled from the house, this time for one hour, for an outburst during House of Representatives Question Time.

As of 2008, Tuckey is the only currently sitting Member of Parliament who first became a member during the government of Malcolm Fraser and the second longest serving Member of Parliament after Philip Ruddock.
