Diena (The Day) is a Latvian language national daily newspaper in Latvia, published since 23 November 1990.

[4] The Latvian businessman Viesturs Koziols 6 August 2010 acquired a 51% stake in the joint-stock company Diena.

[5] However, an investigation by the Latvian Corruption Prevention and Combating Bureau into the "Oligarchs Case" determined in 2011 that the paper in reality was owned by three Latvian oligarchs: Andris Šķēle, Aivars Lembergs and Ainārs Šlesers through the AS Rīgas tirdzniecības osta (JSC Riga Commercial Port, RTO – renamed AS Riga Port in 2022) company.

This was further confirmed with the release of the notorious "Rīdzene Tapes [lv]" in 2017, in which the oligarchs are heard discussing their takeover of the paper.

[8] After long-time chief editor Sarmīte Ēlerte left the paper in 2008, it experienced a frequent change of leadership from 2009 to 2013.
