Peter Neil Slipper (born 14 February 1950) is a former Australian politician who served in the House of Representatives from 1984 to 1987 and from 1993 to 2013, representing the Division of Fisher in Queensland.
He was Speaker of the House of Representatives from 2011 to 2012.
He is the current Bishop of Australia for the Brazilian Catholic Apostolic Church (Igreja Católica Apostólica Brasileira) and an honorary consul for the Brazilian Embassy in Australia.Slipper is originally from Ipswich, Queensland, and studied arts and law at the University of Queensland.
He worked as a lawyer and farmer before entering politics.
Slipper was first elected to parliament at the age of 34, standing as a member of the National Party.
He was defeated after one term, but reclaimed the seat at the 1993 election as a member of the Liberal Party.
During the Howard Government, he served as a government whip and a parliamentary secretary.
After the 2010 election, Slipper fell out with his Coalition colleagues over moves to disendorse him.
He was elected Deputy Speaker of the House of Representatives in September 2010, with the backing of the Labor Party.
In November 2011, he was elected Speaker of the House in place of Labor's Harry Jenkins, thereby giving the Labor minority government an additional number on the floor.
Slipper resigned from the Liberal Party upon taking office, pre-empting moves to expel him.
He was the first independent to serve as speaker since Frederick Holder (1901–1909).
In April 2012, Slipper took a leave of absence from the speakership in order to deal with an Australian Federal Police investigation into his alleged misuse of Cabcharge vouchers, as well as sexual harassment allegations from a former staffer, James Ashby.
He eventually formally resigned in October 2012; he was unsuccessful in his bid to be re-elected as an independent at the 2013 federal election.
Slipper was convicted of defrauding the government in July 2014, but successfully appealed the charges and had his conviction overturned in February 2015.
Ashby dropped his sexual harassment lawsuit in June 2014.
In 2016 he was ordained Bishop of Australia by the Brazilian Catholic Apostolic Church and was instrumental in getting a Continuing Anglican church, the Church of Torres Strait, to join it.
