Benyon contested the Newbury constituency at the 1997 general election but lost heavily to the 1993 by-election incumbent Liberal Democrat David Rendel. Benyon and Rendel contested Newbury again at the 2001 general election, and Rendel came out again as the victor with a reduced majority. He and Rendel again contested Newbury at the 2005 UK general election and Benyon was elected with a majority of 3,460, replacing Rendel. Benyon made his maiden speech on 20 May 2005 and served on the Home Affairs Select Committee from 2005 to 2007, when he became an Opposition Whip. He was the Shadow Minister for the Environment, Food and Rural Affairs from 2009 until the 2010 general election when he entered government. He was also one of the first 15 MPs to support David Cameron's Conservative Party leadership bid. In May 2009, he was listed by The Daily Telegraph as one of the "saints" in the expenses scandal exposed by that newspaper. Benyon was made Parliamentary Under-Secretary of State at the Department for the Environment, Food and Rural Affairs in the first Cameron Ministry. and remained in post until a ministerial reshuffle in October 2013. In 2012, while Wildlife Minister, Benyon refused a request from other MPs that possession of carbofuran, a deadly poison used to kill raptors that is banned in Canada and the European Union, should be made a criminal offence. Green Party MP Caroline Lucas was quoted as saying: "The minister's shocking refusal to outlaw the possession of a poison used only by rogue gamekeepers to illegally kill birds of prey would be inexplicable were it not for his own cosy links to the shooting lobby". In December 2012, Benyon's neighbours complained when Hanson Aggregates were given permission to extract 200,000 tonnes of sand and gravel a year from woodlands on Benyon's family estate, leading it to be described as a 'bombsite'. Benyon said that the estate was controlled by a family trust. In 2013, Benyon succeeded in preventing any cuts in fishing quotas. He said that if British fishermen had their quotas cut they would dump even more fish overboard, and the more fish they are allowed to catch, the better it will be for "the health of our seas". Back in 2004, the Royal Commission on Environmental Pollution proposed that 30% of the United Kingdom's waters should become reserves preventing fishing or any other kind of extraction. Also in
