Facebook founder Mark Zuckerberg has announced the departure of the firm's chief product officer Chris Cox and head of WhatsApp Chris Daniels.
No reason has explicitly been given for their departure, however changes have come shortly after Mr Zuckerberg outlined his plan to transform Facebook into a "privacy-focused platform."
In a separate Facebook post, Mr Cox addressed the recent proposal to shift Facebook further towards private, encrypted communication, saying "This will be a big project and we will need leaders who are excited to see the new direction through."
