AS Watson-owned Rossmann experienced a sales rise of 4.2% in 2010 to CZK2.3bn (£77.9m), according to documents filed at the Register of Companies.

The company edged into the black with a net profit of CZK22.7m (£820,000), up from just CZK1.16m (£41,000) in 2009.

The company attributed the rise mainly to a change in management.

Last year marked only the second year of profit after a long period of losses at the chain, which had been loss-making since the first store opened in 1994.
