(Reuters) - X's global affairs head Nick Pickles said on Thursday he is quitting after a decade with the social media company formerly called Twitter.

Pickles, who joined the company in 2014, said he had decided to leave X several months ago and was working with the Chief Executive Linda Yaccarino through the transition.

"After more than ten years, tomorrow will be my last day at X. It's been an incredible journey," he said.
