The head of O2 Ireland is to step down next month, after nine years in charge of the company.
Chief executive Danuta Gray will be replaced by O2 UK's consumer sales director Stephen Shurrock, with effect from December 1st.
Ms Gray will also leave the Telefónica Europe board at the end of November. However, she will remain as part time non-executive chairman of Telefónica O2 Ireland, and take on an advisory role within Telefónica Europe.
In the past nine years, O2 Ireland has significantly increased its customer base and become the second largest network in the country.
Chief executive of Telefónica Europe Matthew Key said the outgoing chief executive had successfully led the Irish business from the outset, and praised her leadership skills.
"This is a great opportunity for Stephen Shurrock and I’m delighted that we have been able to promote from within the group," he said. "Stephen’s appointment underlines our commitment to Ireland and the ongoing success of our business.”
Mr Shurrock joined O2 in 2000 and has held a number of senior sales and finance roles, including head of commercial finance for Telefónica O2 UK. As head of the consumer sales division, he managed a team of 4,000, and has presided over a significant improvement in the performance of Telefónica O2 UK’s direct business and the online channel.
