Elon Musk fired several Twitter executives after completing his takeover of the company, according to people familiar with the matter, capping an unusual corporate battle and setting up one of the world’s most influential social media platforms for potentially broad change.

Musk fired chief executive Parag Agrawal and chief financial officer Ned Segal after the deal closed, the people said. Musk also fired Vijaya Gadde, Twitter’s top legal and policy executive, and Sean Edgett, general counsel. Spokespeople for Twitter didn’t comment.
