Marks & Spencer is struggling to meet internal sales targets for its stores in China, one of the regions it has earmarked for growth.
According to The Telegraph, the troubled high street retailer has missed its targets across the 14 Chinese stores by as much as 30%.
M&S had previously cited China as one of its key international growth markets.
The retailer declined to comment on specific performance, but told the newspaper stores were trading well.
Earlier this month M&S reported a 3.8% fall in like-for-like sales over the key Christmas trading period.The news had been leaked in the evening before schedule, forcing the retailer to break protocol and publish its figures several hours ahead of time.
The retailer did not split out sales for specific countries or regions but overall international sales climbed by 4.1%.
