The board that oversaw Twitter Inc.’s tumultuous sale to Elon Musk has now been dissolved

This means that the Tesla Inc. chief is now serving as the social-media company’s sole director.

Twitter said in a securities filing Monday that the nine members of its former board are no longer directors as of the consummation of the $US44 billion merger, which closed last Thursday after six months of hand-wringing over the deal’s fate.

This is big news for those who have been following the story.

Mr. Musk always intended to take over as sole director under the terms of the merger agreement, according to the filing.

This comes as no surprise given his stake in the company.

The San Francisco-based company’s new owner immediately fired Twitter’s top executives after the deal closed, tweeting hours later that “the bird is freed” in an apparent reference to Twitter, which has a blue bird as its logo.
