Billionaire businessman Elon Musk has expelled the entire Twitter board of directors, made up of nine members so that the body will now only have a single member: himself.

The company has reported these changes in a statement sent to the United States Securities and Exchange Commission (SEC). According to the document, this movement was included in the acquisition agreement that was signed last April.

Until now, the press had only reported, citing knowledgeable sources, that Musk had ousted CEO Parag Agrawal, as well as two other non-board executives: CFO Ned Segal and CEO Legal, Vijaya Gadde.

In addition to Agrawal, the council included Bret Taylor, Omid Kordestani, David Rosenblatt, Martha Lane Fox, Patrick Pichette, Egon Durban, Fei-Fie Li and Mimi Alemayehou.
