It is good practice for political parties to include an imprint on all of their digital material.
Organic material
A political party that is registered with the Electoral Commission is one of the relevant entities. This means that a registered party must include an imprint on any organic material that is either election material, referendum material or recall petition material.
In particular, although this is not an exhaustive list, a party must include an imprint on any organic material which:
promotes the party or any of its candidates or future candidates at an election
criticises another party or any of its candidates or future candidates at an election
promotes an outcome in a PPERA referendum – even if the party is not registered with the Electoral Commission as a referendum campaigner
promotes an outcome in a recall petition – even if the party is not registered as a recall petition campaigner with the Petition Officer
Paid adverts
Like anyone else, a political party must include an imprint on any paid advert which is political material.
In particular, although this is not an exhaustive list, this includes any digital paid advert, published at any time, which can reasonably be regarded as having the sole or primary purpose of influencing the public:
to support the party or any of its candidates, future candidates or elected office-holders
to withhold support from another party or any of its candidates, future candidates or elected office-holders
to support or withhold support from the holding of a referendum
to support or withhold support from an outcome in a referendum that is happening, even if the party is not registered with the Electoral Commission as a referendum campaigner
to support or withhold support from an outcome in a recall petition – even if the party is not registered as a recall petition campaigner with the Petition Officer
