all main parties have often relied on generous individual or institutional donors. In the Blair years, Labour benefited from wealthy individuals, such as Bernie Ecclestone (chief executive of the Formula One Group) and Lord Sainsbury, although traditionally, and more recently under Jeremy Corbyn, the party has been heavily bankrolled by affiliated trade unions, including GMB and Unite (which gave over £3 million in 2019). The Conservatives have also benefited from generous donors, with the party raising more than £5.67 million in large donations in the first week of the 2019 election campaign, including £200,000 from Lubov Chernukhin, the wife of a Russian business person. Smaller parties can also receive large donations on occasion — business person Christopher Harborne donated £2 million towards the Brexit Party’s 2019 campaign.
