The tradition of allowing free airtime for party election broadcasts is seen as a substitute for paid political advertising on TV and radio, which is banned in the UK.

Ofcom's statement, which will apply to outlets including ITV, Channel 4 and Talksport, follows a consultation into which parties had the "significant levels of support" required to get at least two broadcasts.
