Prime ministerial debates
So finally we can say - they are going to happen. After decades of arguing and a whole host of reasons why they should not happen - there will now be debates during the general election campaign between those who aspire to be prime minister.
After months of negotiation - constructive and good-humoured but often tough and mind-numbingly detailed - an agreement has been worked out between the three broadcasters - ITV, Sky and BBC - and the three largest UK political parties - Labour, Conservatives and Liberal Democrats - over the three debates which will take place, one on each network during each week of the campaign.
The fact that debates have never happened before is an indication of how difficult it is - especially in the pre-election atmosphere - for the broadcasters and the parties involved to find sufficient common ground.
But all involved were very clear that these were events which should and could add to the understanding of voters as they make up their minds.
Each broadcaster will also be looking carefully at how to ensure the obligations of impartiality are properly fulfilled. The BBC will hold subsequent leaders' debates in Scotland, Wales and Northern Ireland, part of a range of measures to ensure that the SNP, Plaid Cymru and the Northern Ireland parties have appropriate opportunities to be heard. There will also be special arrangements in the programming around the BBC debate itself - a week before polling day - to ensure that other parties which have demonstrated that they have some electoral support - UKIP, the Green Party and the BNP - will have their say.
The broadcasters' negotiating panel had a number of ambitions: to involve the public in the debates; to establish a format in which the leaders would actually debate with each other; to make the debates interesting and engaging and not, perhaps, as formulaic and structured as the American presidential debates can be.
For some it's making history - for others it's a constitutional anomaly... whichever, the debates will now happen - and election campaigns may never be the same again in this country.
