The Sun has told its readers to think for themselves and vote for which ever candidate they like the most in today's local elections.
The tabloid, which famously switched its support from Labour to David Cameron's Tories on the day of Gordon Brown's 2009 party conference speech, has always previously endorsed a party.
The Sun's decision will be seen as a blow for the prime minister who is facing a severe bruising in today's elections - with polls showing a surge in support for Ukip.
In its leader column today the paper said: "Today, as 18 million people have the chance to elect new local councils, none of the big four deserves our support.
"Tories, Labour, Lib Dems and yes, even UKIP, have all proved beyond your trust. Read the leaflets. Listen to what all the actual candidates are telling you, and judge them individually."
Cameron said this morning that a vote for the Conservative Party in today’s elections "is a vote to keep your Council Tax bill down".
However in refusing to endorse the prime minister, The Sun slams Tory councils for "unacceptable" behaviour after refusing demands to freeze council tax.
The paper attacks Labour for being "in complete denial about the economic mess they created while in power" and is equally unimpressed with the "two-faced" Lib Dems.
As for Nigel Farage's Ukip? "How can you trust a chaotic mob that mistakenly puts forward so many fruitcakes and extremists?" the paper asks.
Whether The Sun actually has any influence on how people vote is debatable, with some critics noting the paper may simply be hedging its bets as it does not want to get on the wrong side of its readers.
And while Cameron will likely be irritated at losing its endorsement for the local elections, he will perhaps be more worried about Ukip being granted the status of a "big four" party.
The tabloid's dismissive attitude towards Cameron stands in stark contrast to its Obama-style endorsement of the Tory leader in 2009...
