In all cases, digital material must include an imprint for as long as both:
the imprint is required by the law
the material remains published
Material remains published for as long as it is being made available to the public or a section of the public. For example, if a post remains available on your social media channels, then it remains published.
Organic material
For organic material, the imprint is required on material published by a relevant entity for as long as the published material remains election material.
In many cases the imprint will stop being required once the election is over.
For example, a video saying ‘Vote Grey Party on 1 May’ in relation to an upcoming election will cease to be election material after 1 May when the election is over.
