The BBC has announced a number of senior news editorial changes to come into effect after the next general election.
Current editor of the Six O'Clock News Mark Popescu will take over the flagship Ten O'Clock News.
He will replace Jonathan Baker, who becomes world news editor heading the BBC's overseas newsgathering operation. The Six O'Clock News is seeking a replacement for Popescu.
Despite just being announced, the moves have been delayed to ensure a minimum of disruption in the run-up to the election, which is expected to take place in spring. Although it has not yet been called, 3 May is earmarked as a likely date.
BBC head of TV news, Roger Mosey, said Popescu's appointment would not be the catalyst for a change in the Ten O'Clock News: 'All programmes change over time, but this is not going to be relaunched. The profile of the Ten will get ever-higher in the year ahead.'
Baker began editing what was then the Nine O'Clock News in 1997 and was responsible for overseeing last year's move to 10pm.
The editor of BBC Breakfast Andrew Thompson takes up a new role at BBC Sport on 15 January. As head of special projects and development, he will have responsibility for a host of initiatives for the BBC's main channels. A successor is being sought.
