Several key figures behind the Brexit campaign have charted diverse paths since the United Kingdom’s departure from the European Union, with varying degrees of public influence and controversy.

Daniel Hannan, a founding figure of the Vote Leave campaign and one of the original Eurosceptics, maintained a presence in the European Parliament until the Brexit deadline. He subsequently accepted a life peerage from former Prime Minister Boris Johnson, becoming Baron Hannan of Kingsclere. Despite earlier assurances that the UK would remain firmly committed to the single market, Hannan has continued to promote Eurosceptic views through a Sunday Telegraph column and a series of books on Brexit. In 2026, he took on the role of director at the Institute for Economic Affairs, a thinktank linked to the Tufton Street network, which played a significant role in the Brexit movement.

Arron Banks, an insurance broker who financially supported Ukip and spearheaded the Leave.EU campaign, self-identified as one of the “bad boys of Brexit.” Known for flamboyant anecdotes including socializing with the Russian ambassador over vodka, Banks wound up Leave.EU in 2022, reportedly absorbing losses of roughly £7 million. Wealthy from the 2021 sale of his insurance companies, valued at around £100 million, Banks later launched Westmonster, a right-wing news outlet that shuttered in 2019. In 2025, he ran as the Reform UK candidate for mayor of the West of England combined authority, finishing second. His current ventures include ownership of a racecourse and a country estate.

Dominic Cummings, often described as the architect or “mad monk” of Brexit, retreated from frontline government after resigning as Boris Johnson’s chief adviser. He attracted attention during the pandemic for an incident involving a lengthy drive to Barnard Castle. Since then, Cummings has maintained a profile through a Substack newsletter with tens of thousands of subscribers and a small technology consultancy. In 2024, he contemplated forming a new political party aimed at supplanting the Conservative Party but abandoned the plan in 2025 following a private meeting with Nigel Farage, who has publicly criticized Cummings. Cummings remains active online, sharing material from figures such as Elon Musk and controversial activist Tommy Robinson.

Michael Gove’s post-Brexit journey reflects a series of political ups and downs. After a failed leadership challenge against Boris Johnson in 2016 and a dismissal by Theresa May for perceived disloyalty, he was later restored as environment secretary. He lost another leadership bid in 2019 but served as the no-deal Brexit minister before being dismissed again by Johnson in 2022. Since leaving office, Gove has returned to journalism, editing the Spectator magazine from 2024. In 2025, Prime Minister Rishi Sunak appointed him a life peer, designating him Baron Gove of Torry.

Boris Johnson resigned as prime minister in 2022, invoking the Roman figure Cincinnatus to signal his temporary withdrawal from politics. His post-premiership has included corporate speaking engagements reportedly earning £8 million, a Daily Mail column, a bestselling memoir, and co-chairmanship of Better Earth, a consultancy backed by Canadian mining entrepreneur Amir Adnani. However, his business activities have faced scrutiny; leaked documents suggested Johnson sent letters promoting business to Saudi Arabia’s Crown Prince Mohammed bin Salman, raising questions about compliance with post-government employment rules. Johnson’s record as leader, particularly his handling of the COVID-19 pandemic and the Partygate scandal, continues to be examined by the ongoing public inquiry.
