Facebook Chief Executive Mark Zuckerberg apologized to Britons on Sunday over a "breach of trust", taking out full page advertisements in British newspapers after a political consultancy got its hands on data on 50 million users.

"We have a responsibility to protect your information. If we can't, we don't deserve it," said the advert, signed by Facebook founder Zuckerberg.
