A vote calling for Mark Zuckerberg to stand down as Facebook’s chairman is expected to take place at the company’s annual general meeting on Thursday.
Mr Zuckerberg is both Facebook’s chief executive and the chairman of its board of directors.
Those calling for him to step down as chairman say this would help him focus on running the company.
Mr Zuckerberg is very unlikely to lose the vote, because he has 60% of the voting power.
