STOCKHOLM (Reuters) - Volvo Cars' sales rose 13% in May from a year earlier to 68,034 cars, driven mainly by a 31% jump in Europe and helped by strong performance for its fully electric model EX30, the group said on Wednesday.

Sweden-based Volvo Cars, which is majority-owned by China's Geely Holding, said in a statement that sales of fully electric cars were up 37% to account for 48% of group sales globally.
