Some political parties hold fringe events and other meetings at their party conferences. If you receive payments to hold these events, these payments will count as sponsorship.
In this case any payments received with a value of over £500 can only be accepted from a permissible donor. The full value of the payment received should be taken into account and treated as sponsorship, and therefore as a donation to the party. This must be reported by the party if the amount you accept from one source exceeds the donation reporting thresholds.
Please see ‘Which donations and loans do you need to report’ for details of the reporting thresholds.
