Carey (pictured), who began her role in March, will lead the customer and marketing teams across Three’s Irish and UK operations, and will be at the centre of the company’s response to Covid-19.

Three said that Carey would also help increase cooperation between the customer and marketing departments, as well as between the Irish and UK businesses.

Carey was previously at Three Ireland for more than 13 years where she was involved in the company’s strategic commercial agenda.

She also led the business’ consumer commercial activities, including devising and managing its propositions and products portfolio, retail work, ecommerce, sponsorship and all digital and brand activities.

Robert Finnegan, chief executive of Three UK and Ireland, said: “Elaine’s commercial acumen and drive for results will ensure both organisations benefit from her leadership.

“Her depth of experience as well as her extensive sector knowledge will be invaluable as we take Three Ireland and Three UK forward.”
