The senior communications manager at Christian pressure group Evangelical Alliance has quit to start his own business.
Gavin Drake, who joined the EA in 1997, says his company Drake.Comms will work mainly in the Christian and charity sector.
He said: 'I want to improve the relationship between Christian groups and the media. Gone are the days when everything a church leader, like the Archbishop of Canterbury, says is newsworthy. I want to help Christians adapt to modern media.'
Drake.Comms, which also offers services including media training and corporate videos, currently has information service Churches Information For Mission as its only client.
The EA has yet to appoint Drake's replacement, who will report to general director Joel Edwards.
