Debenhams’ Irish business has recorded a 21% rise in full year pre-tax losses to €8.4m (£6m) due to the weakness of the euro against sterling.
Revenues increased marginally for the year to August 31, from €162.1m (£117m) to €163.5m (£118m).
However, the business, which has 11 stores in the Republic of Ireland, lost €2.2m (£1.58m) on its borrowings due to foreign exchange rates, compared to a loss of €197,000 (£142,277) in 2013.
The department store chain said it expected the commercial environment in Ireland to remain challenging this year.
Debenhams entered the Irish market by acquiring the leases for nine Roches Stores for €29m (£20.9m) in 2006. It employs 1,700 people locally.
In total, the group operates 240 stores across 28 countries.
