Any group or individual intending to spend £10,000 campaigning at a referendum must register with the Electoral Commission. Once registered, all campaigners are required to submit an expenditure return providing details of their spending.
In this section you will find summary tables, direct links to the returns and invoices of campaigners at the following referendums:
- UK Parliamentary Voting System (held 5 May 2011)
- National Assembly for Wales (held 3 March 2011)
Alternatively, you can view details of each return item, or extract the spending data from the system using our PEF online registers.
This page only refers to campaigner spending at referendums. To view spending by parties and third parties at relevant elections, please visit our Election expenditure page.
