Communications minister Stephen Carter is expected to leave government, according to a report in The Times.
If confirmed by the government, Carter's departure will be a blow to its plans for implementing a joined up communications policy.
Carter is expected to publish the final Digital Britain report next week. The report addresses problems faced by the telecommunications, broadcasting and publishing sectors that stem from the switch from analogue to digital production and distribution of content now gathering pace.
The Times report quoted Lord Carter saying, "I'm beavering away feverishly on my report, that's my only preoccupation."
The Department for Culture, Media and Sport had not responded to requests to confirm the Times report by the time of writing.
