The Evening Standard has apologised after it published details of the Budget online before George Osborne delivered his statement.
BBC News reports that the newspaper's front page outlined announcements such as the cancellation of a fuel duty rise and a rise in the personal tax allowance to £10,000.
Budget decisions are supposed to be secret before the chancellor speaks.
The newspaper apologised for what it called a "very serious mistake" and removed the online image.
Evening Standard political correspondent Joe Murphy said the newspaper's front page had been published on Twitter in error.
