Political donations in the UK have been subject to comprehensive disclosure since 2001. We study the data produced as part of this disclosure policy to evaluate the role of private and public political finance over time. Total political donations have grown by 250% since 2001, reaching over £100 million in real terms for the first time in 2019. This increase has been driven by donations from private individuals, who now account for approximately 60% of donations in election years compared to 40-50% up to the late 2010s. Furthermore, ‘superdonors’ (those contributing more than £100,000) have been a prominent driver of the rise, increasing their own share from approximately 36% in 2017 to 46% in 2019. We also show that private donations to Labour fell sharply in the final stages of Jeremy Corbyn’s leadership. Overall, these trends have benefited the Conservative Party, leading to an historic resource gap between the two main parties emerging circa 2019. We calculate that the ‘resource gap’ between parties now stands at approximately £27 million compared to an historic average of £8-10 million (even when taking account of publicly-funded ‘Short’ money provided to the Opposition).
