The Spanish leaking scandal
Barcepundit explains,

Someone doesn't like that newspaper El Mundo has been publishing embarrasing information (such as this, this, this, this, this, this and this, to point out just a few, and don't miss the last one: "the wife of Syrian-born PSOE member and imprisoned terrorist Mouhannad Almallah in 2003 charged her husband with domestic abuse, and informed police about her husband's plan to blow up the Kio Towers office buildings in Madrid"; more here) so they're threatening the editor with jail unless he hands the judge all the information he has on the case.

In some cases it means that the internal code in documents and data DVDs originally given by the court to the affected parties and their attorneys will allow the judge to know who the leaker is.

Previous leaks published by El Pais, virtually the Socialist party house organ, which helped the Socialist government's case naturally were not theatened with prosecution (link in Spanish)

More details to come, that is, if the editors aren't in jail by then.
