The Political Donations and Regulated Transactions (Anonymous Electors) (England and Wales) Regulations 2006
Political donations may only be accepted from an individual if that person is registered in an electoral register. Similarly, a registered political party may only enter into a regulated transaction (as defined by section 71F of the Political Parties, Elections and Referendums Act 2000 (c. 41)) with an individual if that individual is registered in an electoral register. These Regulations prescribe the form of evidence required to establish that a donor who has an anonymous entry in an electoral register is indeed a registered elector.
