Campaigners and politicians are demanding action to "rein in the wild west of election campaigning", following news that Vote Leave will be fined just £61,000 for breaking the rules during the EU referendum.
Seven political parties and two non-party campaigners reported spending a total of just under £40 million at the 2017 UK Parliamentary general election, as shown in new figures published by the Electoral Commission.
Details of £18,000 in fines for the Liberal Democrats have been published by the Electoral Commission; this follows an investigation that found the party failed to deliver a complete and accurate spending return as a permitted participant at the EU Referendum.
