This is a list of political scandals in the United Kingdom in chronological order. Scandals implicating political figures or governments of the UK, often reported in the mass media, have long had repercussions for their popularity. Issues in political scandals have included alleged or proven financial and sexual matters,^[1] or various other allegations or actions taken by politicians that led to controversy.^[2][3][4] In British media and political discourse, such scandals have sometimes been referred to as political sleaze since the 1990s.^[4] Notable scandals include the Marconi scandal, Profumo affair and the 2009 expenses scandal.

• In 2002, Edwina Currie revealed that she had had an affair, beginning in 1984, with John Major before he became Prime Minister of the United Kingdom. This was criticised as Major had frequently pushed his Back To Basics agenda (see above), which was taken by the media as a form of moral absolutism.
• The Burrell affair – allegations about the behaviour of the British royal family and their servants with possible constitutional implications. (2002)
• Ron Davies stood down from the Welsh assembly following accusations of illicit gay sex. Davies had claimed he had been badger-watching in the area. (2003)^[15]
• The apparent suicide of Dr. David Kelly and the Hutton Inquiry.

The government was cleared of wrongdoing, while the BBC was strongly criticised by the subsequent inquiry, leading to the resignation of the BBC's chairman and director-general.
• In April 2004, Beverly Hughes was forced to resign as minister for Immigration, Citizenship and Counter Terrorism when it was shown that she had been informed of procedural improprieties concerning the granting of visas to certain categories of workers from Eastern Europe.

• In 2005, David McLetchie, leader of the Scottish Conservatives, was forced to resign after claiming the highest taxi expenses of any MSP.^[17] These included personal journeys, journeys related solely with his second job as a solicitor, and Conservative Party business, for example travel to Conservative conferences.

• Cash for Honours (2006). In March 2006 it emerged that the Labour Party had borrowed millions of pounds in 2005 to help fund their general election campaign.

By resigning Laws became the shortest serving Minister in modern British political history with less than 18 days' service as a Cabinet Minister.

• On 14 October 2011 Secretary of State for Defence Liam Fox resigned from the Cabinet after he "mistakenly allowed the distinction between [his] personal interest and [his] government activities to become blurred" over his friendship with Adam Werritty.

• On 20 November 2014 Emily Thornberry resigned her shadow cabinet position shortly after polls closed in the Rochester and Strood by-election. Earlier in the day, she had received criticism after tweeting a photograph of a house in the constituency adorned with three flags of St. George and the owner's white van parked outside on the driveway, under the caption "Image from #Rochester", provoking accusations of snobbery. She was criticised by fellow Labour Party MPs, including leader Ed Miliband who said her tweet conveyed a "sense of disrespect".^[32][33]
• Namagate, involving allegations that First Minister of Northern Ireland Peter Robinson may have financially benefitted from a deal with National Asset Management Agency (NAMA).^[34]

• In September 2015, Lord Ashcroft published a biography of David Cameron, which suggested that the then Prime Minister took drugs regularly and performed an "outrageous initiation ceremony" which involved inserting "a private part of his anatomy" into the mouth of a dead pig during his time in university. This became known as "piggate".^[35] It also led to questions about the Prime Minister's honesty with party donors' known tax statuses as Lord Ashcroft suggested he had openly discussed his non-domiciled status with him in 2009, earlier than previously thought.^[36]

• In 2017 the contaminated blood scandal, in which many haemophiliacs died from infected Factor medicine, hit the headlines and Parliament with allegations of an "industrial scale" criminal cover-up.^[37] MP Ken Clarke retracted remarks from his autobiography^[38] relating to the scandal and a public inquiry is now underway.
• The Renewable Heat Incentive scandal in Northern Ireland, in which Arlene Foster set up a green energy scheme but failed to introduce cost controls, creating perverse incentives which eventually led to a £480m bill to the Northern Ireland budget.^[39] There were allegations that members of the Democratic Unionist Party attempted to postpone the closure of the scheme, which gave way to a spike in applications and causing the public purse millions of pounds. In January 2017, the scandal caused the resignation of the deputy First Minister, Martin McGuinness, after Foster refused to stand aside as First Minister pending an investigation, collapsing the Executive Office and triggering an early election of the Northern Ireland Assembly. The resulting political rifts meant the Assembly did not meet again until 2020.

• The 2018 Windrush scandal, involving members of the Windrush generation being wrongly detained, deported, or threatened with deportation which caused the resignation of the then Home Secretary, Amber Rudd.^[40]

• The Dominic Cummings scandal, where Dominic Cummings, chief strategist of prime minister Boris Johnson, broke COVID-19 pandemic restrictions during the UK's first nationwide lockdown while experiencing symptoms of the disease. Cummings and Johnson rejected calls for the former to resign. It was suggested that the scandal undermined the public's compliance with pandemic restrictions.^[41][42]
• The Alex Salmond scandal concerned how the Scottish Government, led by incumbent first minister of Scotland Nicola Sturgeon, breached its own guidelines in its investigation into the harassment claims against Sturgeon's predecessor as first minister, Alex Salmond. The Scottish Government lost a judicial review into their actions and had to pay over £500,000 to Salmond for legal expenses.^[43] Salmond claimed that senior figures in Sturgeon's government and the ruling Scottish National Party (SNP) conspired against him for political reasons.^[44][45] Critics accused Sturgeon of breaking the ministerial code which resulted in calls for her resignation.^[43] Sturgeon disputed the allegations, arguing that while mistakes had been made, her government acted appropriately.^[44]

• The Greensill scandal, in which former prime minister David Cameron approached a number of government ministers on behalf of Greensill Capital to lobby for the company to receive Covid Corporate Financing Facility loans.^[46]
• The Sun published pictures and then video of leaked CCTV footage from inside the Department of Health of health secretary Matt Hancock and Gina Coladangelo kissing in a breach of COVID-19 social distancing guidance. Boris Johnson accepted Matt Hancock's apology and stated that he "considers the matter closed",^[47] but Hancock resigned as health secretary the following day.^[48][49]
• In November 2021, the Parliamentary Commissioner for Standards found that Conservative MP Owen Paterson had broken paid advocacy rules, but instead of approving his suspension, the government enforced a three-line whip on Conservative MPs to pass a motion that the investigation was "clearly flawed". After an outcry from opposition parties, the government made a U-turn and Paterson resigned.^[50][51]
• Partygate, involving social gatherings by Downing Street and Conservative Party staff during COVID-19 restrictions in late 2020.^[52][53][54]

• Neil Parish, Conservative MP for Tiverton and Honiton, was forced to resign in April after it was discovered that he had watched pornography in the House of Commons on at least two occasions.^[55]
• Chris Pincher scandal: Chris Pincher, the deputy chief whip of the Conservative Party, resigned on 30 June following allegations about him groping two men.^[56] Further allegations of harassment emerged against Pincher, along with claims that prime minister Boris Johnson had already been informed of his behaviour.^[57] The incremental effect of this and other recent controversies led to the resignation of 59 Conservative politicians, including Rishi Sunak as chancellor and Sajid Javid as health secretary. This in turn led to Boris Johnson committing to resign as leader of the Conservative Party, and thus as prime minister when his replacement as leader had been chosen by his party.

• Michael Matheson iPad scandal: Scottish Health Secretary Michael Matheson incurred nearly £11,000 in roaming charges after taking a Scottish Parliamentary iPad on a family holiday to Morocco. When this was publicised, Matheson initially attempted to claim the charges as a parliamentary expense, but later admitted that the iPad had been used by his sons to stream football matches and agreed to personally pay back the full cost of the data roaming bill. Following an investigation by the Scottish Parliament Corporate Body, Matheson resigned as Health Secretary in February 2024. Matheson was subsequently banned from Holyrood for 27 days and had his salary withdrawn for 54 days, the heaviest sanction ever given to an MSP.^[58]

• In March 2024, The Guardian reported that Frank Hester, the largest ever donor to the Conservative Party, had made comments in a 2019 company meeting about the MP Diane Abbott. The paper reported that he said that looking at Abbott makes you "want to hate all black women" and that she "should be shot", as well as making comments about a female executive from another organisation, saying "it would be much better if she died", and about his own Asian female employees, saying "we take the piss out of the fact that all our Chinese girls sit together in Asian corner".^[59]
• Election betting scandal: Following the scheduling of the 2024 general election for 4 July, it was discovered that Craig Williams, Parliamentary Private Secretary to Prime Minister Rishi Sunak, had placed a £100 bet on the election being in July. Further investigation uncovered multiple similar bets made by Conservative Party members and MPs, including cabinet minister Alister Jack, as well as police officers on Sunak's protection detail.^[60] Both the Gambling Commission and the police are investigating whether any criminal offences were committed by people involved in the scandal.^[61]
