A party political broadcast (also known as a party election broadcast or party conference broadcast depending on the date of broadcast) is a short television or radio broadcast made by a political party.
In the United Kingdom, political advertising on television or radio is illegal, but parties are instead allocated broadcast slots across the traditional terrestrial TV channels. On a given day, a given party will be allowed to broadcast a piece about five minutes long.
A similar format exists in the Republic of Ireland, though due to more smaller parties being represented in the Dáil Éireann time given to those smaller parties may be as little as one or two minutes.
