Former heads of the UCO have provided testimony that contradicts statements made by Mercedes González. They confirmed that a judge asked them to take a low profile in a case involving the brother of Sánchez. They also denied being informed about certain contacts related to the 'fontanera' case.

The testimony was given to Judge Santiago Pedraz of the Audiencia Nacional. Further details about the case and the testimony are available from El Mundo. The investigation is focused on alleged maneuvers to dismiss cases that could harm the Government and the PSOE.
