Marks & Spencer is allegedly struggling in China amid reports that it is missing its internal sales targets in the country.

The retailer's Chinese sales are said to be 30% lower than internal targets set by executives, The Telegraph claimed.

Earlier this month, the retailer posted worse than expected third quarter sales figures, with general merchandise taking the majority of the hit.

International sales rose 4.1% on a constant currency basi, but, in reality, were flat due to weakness in the euro.

This is the second leak to come out of the retailer this month, with Marks & Spencer forced to release its Christmas trading update early after the results were leaked.

Conspiracy theorists have suggested the leak could be an internal attempt to discredit chief executive Mark Bolland or a rival or potential bidder seeking to destabilise the business.
