Eustice was elected as Member of Parliament for Camborne & Redruth on Thursday 6 May 2010 with a majority of 66 votes over the
Liberal Democrat incumbent
Julia Goldsworthy. The result was only confirmed after a
recount. He had the second smallest majority of any Conservative elected at the 2010 election, with only
Dan Byles 54 vote majority in
North Warwickshire being lower, and the fourth smallest majority of any MP. He made his maiden speech in the House of Commons on 24 June 2010: "It is a special honour for me to represent my home town. I was brought up between Camborne and Hayle, in Cornwall, and my family have lived and worked in the area for more than 400 years. When one has such deep roots in a constituency, one feels a special responsibility for its long-term future." Later in the same speech he said "My No. 1 priority for the area will be economic regeneration." Eustice was asked to take a leading role in the 2011 "
No to AV Referendum" campaign, reportedly as a result of his work for Business for Sterling and the "No" Group, which campaigned to keep the pound and against the adoption of the Euro as currency in the UK. In September 2011, he argued that
Cornwall's heritage should be administered by a Cornish organisation rather than
English Heritage. In September 2011, Eustice, with two other Conservative MPs
Andrea Leadsom and
Chris Heaton-Harris launched the Fresh Start Group to examine the options for a new UK-EU relationship. He wrote an article in
The Guardian on 10 June 2012, which argued for the UK to remain within the EU, but to seek reform from within. On 10 July 2012 the Fresh Start Group released a research paper, which according to
The Financial Times, called for "reducing the overall size of the EU budget, overhauling the
Common Agricultural Policy to which the UK contributes about £1bn a year and repatriating structural funds." as part of the "301 Group" of newer MPs. urging both journalists and politicians to back a
royal charter. Reacting to the letter, Conservative writer
Tim Montgomerie argued that greater press regulation was now more likely. Eustice was a member of the
Environment, Food and Rural Affairs Select Committee from 12 July 2010 until November 2013 and of the Privacy and Injunctions (Joint Committee) between July 2011 and March 2012. In April 2013, Downing Street announced Eustice's appointment to the "Number 10 Policy Board", to advise
David Cameron on Energy and Environment issues. Eustice was appointed to work on Conservative rather than Coalition policies, with backbenchers including
Jo Johnson,
Jesse Norman, and
Peter Lilley. He was criticised by
The Daily Telegraph in November 2012 for signing a letter calling for tougher regulation of the press on the grounds that he had previously been the subject of negative media coverage. The newspaper reported that he had previously been nicknamed "Useless" by some sections of the press and had a difficult relationship with the media because of its treatment of David Cameron when they were working closely together. Eustice responded that the existing system was flawed and that "it would be better by far to have credible and independent regulation much earlier in the process." On 7 October 2013, Eustice was appointed Parliamentary Under Secretary of State in the Department for Environment, Food and Rural Affairs, with responsibility for farming and food, marine and fisheries, and animal health. On 11 May 2015 he was promoted to Minister of State for Agriculture, Fisheries and Food. In May 2017, the Crown Prosecution Service said that while there was evidence of inaccurate spending returns, it did not "meet the test" for further action. In August 2016, Eustice was one of two Conservative environment ministers who were accused by environmental campaigners of having a conflict of interest over receiving subsidies on their family businesses whilst being involved in developing the plans for the replacement system to the EU farming support. He was re-elected at the
2015 general election and
2017 general election. He supported Leave in the
2016 EU membership referendum. On 28 February 2019, Eustice resigned from his position as Minister of State for Agriculture, Fisheries and Food, in protest at Prime Minister Theresa May's promise to allow MPs a vote on delaying Brexit if her deal fails to get through. Eustice stated "it would be dangerous to go to the EU cap in hand at the 11th hour and beg for an extension".
Secretary of State for Environment, Food and Rural Affairs On 13 February 2020, Eustice was appointed as the new
Secretary of State for Environment, Food and Rural Affairs, replacing
Theresa Villiers. Eustice called the post his "dream job". Later in February 2020, in an interview on
Sky News, Eustice refused to guarantee that the UK government would ban
chlorinated chicken outright as part of a
UK–US trade deal. He described chlorine washes on chicken as "a very outdated technology" and said the UK government was committed to high standards for food safety and for animal welfare, saying there were "no plans" to change
food standards laws. Eustice was criticised for an alleged closeness to
the farming industry and for his enabling of
badger culling. Prime Minister
Boris Johnson signalled an end to badger culling after Eustice had overseen an expansion in licenses for it in 2020. In late 2020, Eustice repeatedly expressed support for the
Internal Market Bill, despite the latter representing a breach of formal commitments made by the Conservative government of which he is a part, and also a breach of
international law. He also said that a
Scotch egg was a
substantial meal in law, so long as there is
table service. In December 2020, during a
Sky News interview, Eustice was shown footage of, and asked for his views about,
Millwall F.C. supporters booing players
taking a knee. Those supporters' behaviour had already been condemned as racist by the
English Football League and the
Football Association. Eustice declined to condemn the supporters' behaviour or to recognise it as racist, stating that he had not seen the incident and that "the issue of race and racial discrimination is something that we all take very seriously". In January 2021, Eustice broke his government's pledge to retain a ban on the use of
neonicotinoid pesticides, which have been implicated in
pollinator decline. In May, Eustice announced a radical new animal welfare strategy to be introduced as the Kept Animals Bill, Animal Welfare (Sentience) Bill and Animals Abroad Bill. These bills would make the microchipping of cats compulsory, recognise the sentience of vertebrate animals and ban live animal exports for fattening and slaughter. He also announced the government would look at banning practices such as importing
foie gras, inhumane poultry caging and inhumane penning of pregnant and suckling pigs. Eustice was dismissed by incoming
Prime Minister Liz Truss on 6 September 2022. ==Post-parliamentary career==
