Profile: Craig Oliver
Craig Oliver, who has been selected to replace Andy Coulson as David Cameron's communications chief, has worked in broadcasting for almost two decades.
The 41-year-old has resigned from his job as controller of English services at BBC Global News.
In this role he was responsible for the World Service, BBC World News and the News website outside the UK.
There had been wide speculation about who would replace Mr Coulson, a former editor of the News of the World, in Downing Street.
Many high-profile journalists were mentioned by commentators, but Mr Cameron appears to have opted for a more backroom figure rather than a household name following the embarrassment caused by the ongoing saga over phone-hacking at Mr Coulson's old newspaper.
When news of the appointment broke, it came as a complete surprise to many as his name had not been mentioned in any of the lists of possible candidates put together by media commentators.
