Nick Reilly has been made the new president of Vauxhall/Opel.
Wales-born Reilly, 59, has been heading GM's restructuring of its Opel/Vauxhall operations since former GM Europe president Carl-Peter Forster quit last month
He will now leave as head of GM's international operations, his previous post, to become GM Europe president.
“I'm extremely pleased to be able to lead Opel and Vauxhall through the current difficult times and into a sustainable future,” Reilly said in a statement.
“As a European, I'm totally committed to Opel/Vauxhall's future success. There are a lot of challenges ahead, and it won't be an easy ride, but I'm convinced that all ingredients are there to make it work.”
Tim Lee will take over Reilly's role as president of GM's international operations, overseeing GM's Asia-Pacific, Latin America, Africa, and Middle East operations.
