Robbie Marsland has been head of comms and campaigns since the end of 2002, but took over as UK director last month after Phyllis Campbell McRae decided not to return from maternity leave.
His role will now be split across two new positions.Marsland said: ‘There will now be a comms manager and a campaigns manager reporting to me. I will still be actively involved in both functions as well as running the UK office.'
Press officer Rosa Hill has already been promoted to the comms manager position; interviews for the campaigns manager role will be held later this month.
The charity is currently involved in three campaigns: stamping out the wildlife trade, protecting marine environments and ensuring the UK foxhunting ban is implemented.
The organisation is also planning press activity around its Song of the Whale research vessel, which will be on display at the Southampton Boat Show in September.
Marsland has just returned from Sakhalin Island in the Russian Far East, where he was highlighting the plight of the remaining 100 Western Pacific Grey Whales.
