The Conservative Party is facing questions over more than £3.6m it spent in the run-up to the 2019 general election without explaining what it paid for.
Researchers from the International Institute for Democracy and Electoral Assistance were unable to work out what more than a fifth of the Tories’ national spend had actually been used for because of unclear or even missing invoices.
The Tories were responsible for almost 60% of the unclear invoices in the Electoral Commission’s database for the 2019 election, the team of researchers found.
