JLR Monday reported 12.3 per cent decline in global sales at 57,114 units in September, hit by lower demand in China, the auto major said.
The company's sales in China declined by 46.2 per cent during September as compared to the same month last year as ongoing market uncertainty resulting from import duty changes and continued trade tensions held back consumer demand.
