Miguel Bosé, the controversial singer, is facing backlash for his participation in an event titled "Freedom of Expression and Therapeutic Freedom" in Mallorca, organized by Josep Pàmies and his group, Dulce Revolución.

This event promotes the use of chlorine dioxide, a bleach-like substance, as a treatment for various ailments, including autism.

The Balearic government and the Official College of Physicians have condemned the event, warning that they will monitor for any unauthorized health practices.

A complaint has also been filed by the Círculo Escéptico, urging authorities to prevent the event due to its promotion of pseudoscientific therapies.

Despite the criticism, the organizers claim all tickets have been sold, indicating strong interest in the controversial gathering.
