Snowdon, currently on a career break in the US, has applied for voluntary redundancy, it is believed, as the DTI moves to shed 25 per cent of its jobs over the next two years in line with civil-service cutbacks.
Snowdon leaves after two years in the post and four years with the department. DTI director of comms Sheree Dodd confirmed she will be looking to replace Snowdon after his departure in the new year.
Snowdon was unavailable for comment as PRWeek went to press.
l DTI energy-desk press officer Neil Burrows is to join oil and gas firm BG Group as comms manager for global markets.
