Pedro Sánchez, came to power in 2018 promising to regenerate public life, and holding that those convicted of corruption should not benefit from a pardon.
The government has done exactly the opposite, granting measures of grace to people convicted of corruption.
These pardons convey the idea that there's a final instance where you can obtain forgiveness after the courts, increasing citizens' mistrust.
These actions occur at a time when corruption is causing serious problems to the PSOE and La Moncloa.
The Government was not required to grant Borràs the pardon, but chose to do so.
Conclusion: This change in behavior shows that Sánchez's promises are not based on conviction, but on their convenience for maintaining power.
