The head of global affairs at X is departing from Elon Musk’s social media platform, leaving a significant gap in leadership as the company faces increased global scrutiny.

Nick Pickles, one of the few senior leaders who transitioned to X following Musk’s $44 billion acquisition, announced that he made the decision to leave several months ago and expressed gratitude to Chief Executive Officer Linda Yaccarino for her support. “After more than ten years, tomorrow will be my last day at X,” he shared on X. “It’s been an incredible journey.”

Having joined the company in London in 2014, Pickles is exiting during a critical period for X and the broader tech industry. He is well-known among government officials worldwide and has represented Twitter in various discussions.

Last week, a Brazilian judge prohibited X as part of a broader initiative against misinformation, following a contentious exchange between the judiciary and Musk.

Since Musk's acquisition in 2022, scrutiny of X has increased, particularly after the dismissal of thousands of employees, including many responsible for communication and misinformation management on the platform.

On Wednesday, Ireland’s Data Protection Commission revealed that X has agreed to cease processing the personal data of European users for training its AI chatbot, Grok. Additionally, X has recently encountered disputes with the Australian government regarding footage of a stabbing incident in Sydney.

X did not provide an immediate response to a request for comment after regular business hours.
