Ofcom have announced their decision on party election broadcasts:

After carefully assessing consultation responses, evidence of electoral performance and trends in opinion polling data up to and including February 2015, Ofcom has added UKIP to the list in England and Wales for the May 2015 elections.

Based on the evidence, the Green Party (including the Scottish Green Party) and TUV have not been added to the list on this occasion. 

As a result, those parties entitled to a minimum of two party election broadcasts are:

In Great Britain, the Conservative Party; the Labour Party; and the Liberal Democrats.

In Scotland, the Scottish National Party (SNP).

In Wales, Plaid Cymru.

In Northern Ireland, the Alliance Party; the Democratic Unionist Party; Sinn Féin; the Social Democratic and Labour Party; and the Ulster Unionist Party.

In England and Wales, UKIP.

Leaving the Green Party with only one on ITV, Channel 4 and regionals. The BBC are not covered by Ofcom…
