Stellantis has appointed Alison Jones as country manager UK and senior vice-president for Peugeot, Citroen, DS Automobiles, Fiat, Fiat Professional, Abarth, Jeep and Alfa Romeo.
She was appointed as group managing director of Peugeot, Citroen, DS Automobiles in the UK and senior vice-president for Groupe PSA in February 2019.
Jones previously held senior roles in the VW Group, including managing director for Volkswagen and is a vice-president for the Institute of Customer Service.
She has also recently been appointed as vice-president for the SMMT.
This appointment follows the announcement that Paul Willcox has become the new managing director of Vauxhall Motors.
Jones and Willcox will report to Maxime Picat, chief operating officer, Enlarged Europe, at Stellantis.
Arnauld Leclerc is appointed global head of brand strategy and performance for Alfa Romeo, reporting to Jean-Phillip Imparato, chief executive officer for Alfa Romeo.
Stellantis was formed at the beginning of the year after the merger of PSA Group and Fiat Chrysler Automobiles (FCA) was approved by shareholders from both companies.
The resulting business is the world's fourth largest car maker, with combined revenues of £144 billion.
Both businesses agreed to a 50:50 merger and will bring together their capabilities in the technologies shaping the new era of sustainable mobility, including electrified powertrain, autonomous driving and digital connectivity.
The new entity expects to sell more than 8.7 million vehicles each year.
