Aldo Liguori, corporate vice-president and head of global comms and PR, is to step down at the end of October after seven years with the mobile phone giant.
Sony Ericsson is expected to name Liguori’s successor shortly. It is understood that a successor will be in place at some point in March, with Liguori staying on until the autumn to manage the transition.
He said: ‘I am pleased to be leaving the communications function and the wider company in a very strong and solid position for my successor to build upon.’
Liguori moved to London to take up his role at Sony Ericsson in 2004. Before that, he headed comms for Sony Europe in Berlin for four years and has also headed international PR for Sony Corporation in Tokyo.
He is not understood to have a specific job to go to but is expected to take a global consumer comms role outside of the telecoms and electronics sectors.
Sony Ericsson returned to profit during 2010 and earlier this month unveiled the Xperia Play phone, the first phone with PlayStation gaming controls built into the handset.
