Shareholder advisors are also recommending investors withhold the renomination of long-time Mr Zuckerberg ally Marc Andreessen, due to his investments in companies that were later acquired by Facebook. The votes come just over a year after the Cambridge Analytica scandal which raised questions over Facebook's handling of user data. The company has also been embroiled in controversy over a data breach in September last year and faced scrutiny of its management, including Mr Zuckerberg and chief operating officer Sheryl Sandberg. Earlier this month, Facebook co-founder Chris Hughes, who left the company in 2007, criticised Mr Zuckerberg's "staggering" power and called for the company to be broken up. Facebook is advising votes against all shareholder proposals. In its response to the motions, Facebook said: "We believe that our capital structure is in the best interests of our stockholders and that our current corporate governance structure is sound and effective."
