How to become a lead campaigner or a minor campaigner
There is no limit on the number of lead campaigners in a joint campaign. There is also no limit on the number of minor campaigners who can work with any one lead campaigner in a joint campaign. However, a minor campaigner cannot also be a lead campaigner in the same campaign.
Lead campaigners must be registered, while minor campaigners must be unregistered.
If a minor campaigner registers with us (for example because they incurred £10,000 of their own regulated spending outside of the joint campaign) then they cease to be a minor campaigner. Any joint campaign they are in, with a lead campaigner or with any other minor campaigners, reverts to being an ordinary joint campaign.
You should use Form TP7: Notification of Lead Campaigner, to notify us of the appointment of a lead campaigner and any minor campaigners.
