Jesús de Polanco

More conservative and clerical rivals in the media, such as the newspapers ABC and El Mundo or the radio station COPE, have at times accused Polanco's related media of having a monopoly on Spanish information and being capable of presenting biased reporting.

Some of these have also accused PRISA of influencing public opinion against the People's Party (PP) government's management and response to the Madrid train bomb attacks of March 11, 2004.

The Government conceded this license and Cuatro (TV) channel started broadcasting in November 2005.

In 2007, responding to the accusations of his media being biased, Polanco said that it was difficult to be impartial when there is a party which would do anything to go back into power.

The Spanish People's Party reacted by promoting a boycott of all Polanco's media channels and shareholders.
