Creagh was elected as a councillor for the London Borough of Islington in 1998, representing Highbury West ward (named Highbury from 1998 until 2002), and served as the Labour Group Leader for five years during a period when the party was in opposition locally.[6][7] During this time, she knocked on doors and ran a campaign office for future party leader Jeremy Corbyn.[8] She stood down from Islington Council in 2005 upon her election to parliament.[9]
In 2002, Creagh formally alleged cronyism in the appointment of the Islington Council chief executive by five Liberal Democrat councillors, thus triggering an investigation by the Standards Board for England. After the longest-ever investigation by the Standards Board, her complaint was rejected. Creagh was criticised by the tribunal as being "heavily influenced by her political motives" and that she was an "insensitive witness, lacking in balanced judgment and one who was prepared to make assumptions about honesty and integrity of others without any proper basis".[10] However, Creagh defended herself, saying she "blew the whistle because I believed the Liberal Democrats were not meeting the standards we expect from people in public office. I invite people to look at my evidence and draw their own conclusions".[10] The Liberal Democrat councillors involved lost their seats at the 2006 elections when their party lost control of the council.[11]
Creagh successfully introduced a Children's Food Bill in 2005 which sought to introduce minimum nutritional standards for all school meals and take fizzy drinks and sugary snacks out of school vending machines. Both of these measures were accepted by the government and became law under the Education and Inspections Act 2006.[15]
Creagh launched a campaign in 2006 aimed at preventing scalding injuries in the home. She brought together medical experts, campaign groups and victims of scalding injuries to lobby the government to change the building regulations to prevent people being severely scalded by hot water. The coalition pressured the government to make the fitting of a water temperature regulating device, such as a thermostatic mixing valve (TMV), compulsory in new bathrooms in England. In 2009, after a three-year "Hot Water Burns Like Fire" campaign, the Labour government confirmed TMVs were to be a standard fitment in all new bathrooms from April 2010.[20][21]
In 2009, as Vice Chair of the All-Party Parliamentary Group for the Prevention of Genocide and Other Crimes Against Humanity, Creagh called on Justice Secretary Jack Straw to tighten British Law so people accused of genocide could be prosecuted in the UK. She said there was an "impunity gap" which allowed people accused of terrible crimes in places like Rwanda and Bosnia to escape justice and live freely in Britain.[22] As a result of this, the government agreed to amend the Coroner's and Justice Bill to tighten the law so anyone suspected of war crimes anywhere throughout the world since 1991 and resident in the UK could be prosecuted in UK courts.[23]
On 8 October 2010, Creagh was appointed Shadow Secretary of State for Environment, Food and Rural Affairs.[24] In February 2011 she secured a House of Commons debate[25] on the government's plans to sell off 85% of public forestry. The government subsequently abandoned these plans,[26] it having become clear that the public "were not happy with the proposals".[27] In 2011, Creagh criticised the decision by the Department for Environment, Food and Rural Affairs to cut flood defence spending in real terms by 32%.[28] In addition to her involvement in campaigns calling for the banning of wild animals performing in circuses,[29] she has opposed the government's policy of badger culling, claiming it was "anti-science" and that the option of vaccination should be explored.[30] At the Labour Party's Annual Conference in September 2011, Creagh launched the campaign Back the Apple.[31] with Unite the Union. The campaign opposes the government's plan to abolish the Agricultural Wages Board[32] which sets wages and conditions for thousands of agricultural workers.
In 2013, Creagh was appointed Shadow Secretary of State for Transport.[33] On 24 March 2014 she and Jamie Hanley opposed the train fares price increases in New Pudsey proposed by Patrick McLoughlin. The opposition spread throughout 18 West Yorkshire stations, forcing McLoughlin to scrap the plan.[34] The same day she took part in the minibus opening ceremony which was hosted by Colchester Community Volunteer Service[35] and two days later accused the government of donating their time into privatising East Coast Main Line instead of worrying about high fare prices.[36]
On 14 May 2015, Creagh announced her candidacy for Leader of the Labour Party after Ed Miliband's resignation following Labour's general election defeat.[38][39] On 12 June, Creagh announced that she was withdrawing from the leadership contest. At the time of her announcement, she had secured about 10 nominations from Labour MPs, fewer than any of the other remaining candidates and well short of the 35 required to take part in the final ballot.[40] After the election of Jeremy Corbyn as Labour leader in September 2015, Creagh resigned from the frontbench.[41]
Return to the backbenches: 2015–2019
On the 1 December 2015 edition of BBC programme Newsnight, Creagh argued in favour of military action in Syria, stating: "ISIL pose a clear threat to Britain", "it makes no sense to turn our planes back at the Syrian border" and "we must act to keep our country safe".[42]
Creagh voted against the triggering of Article 50 in February 2017.[44] She went on to state blue passports were "not worth £50 billion and crashing the economy" and the UK leaving the EU would be bad for the planet, and "more than the harm" done by Donald Trump.[45][46] In 2017, a constituent was jailed for harassment after sending Creagh far-right influenced material. Creagh's security later was stepped up after property damage and a "credible threat" in relation to her opposition to Brexit.[47]
During the 2017 general election, Creagh was reported as writing to constituents to say that her team had been "speaking to people in your street" who had told them they had "more confidence in Theresa May as Prime Minister than Jeremy Corbyn", predicted a large Tory majority and called for a vote for them as individuals while promising to "work for a Labour Party that can once again regain your confidence." The letter was similar to ones sent by Joan Ryan and Gavin Shuker.[48]
In November 2018, Creagh expressed sympathy for Labour MP Angela Smith after Smith's Constituency Labour Party passed a vote of no confidence in her.[49] In February 2019, Creagh was invited to join breakaway Labour MPs when they formed The Independent Group, later Change UK, but declined.[50]
In June 2019, Creagh called on the Labour Party to express "full-throated support" for a second EU referendum.[51] She was later defeated at the 2019 general election by the Conservative candidate Imran Ahmad Khan. In an interview with Channel 4 News, Ahmad Khan attributed his success during the election to "Islington Remainers" who had branded Leave voters "stupid, uneducated, racist or wrong".[52] Ahmad Khan was later was forced to resign the seat after being convicted of sexual offences against a child.
In June 2020, it was announced that she would become chief executive of Living Streets, a British charity for pedestrians, effective September 2020.[57][58]
