Primark continues to defy problems on the High Street. It is expected to raise like-for-like sales in the UK by 1.5% for its financial year, which ends on 15 September.
However, Primark has operations across Europe and like-for-like sales in northern Europe fell, due to "unseasonable weather during three periods this year".
Primark is owned by Associated British Foods (ABF), which earns two-thirds of its profits outside the UK. It said that due to currency moves it expects extra costs of £20m.
However, ABF said its full year trading outlook remains unchanged.
