Nevertheless ABF warned that the company has prepared for potential disruption in the months ahead, in particular Brexit.
The company added: "Our businesses have completed all practical preparations should the UK exit the Brexit transition period with or without a trade deal. Primark operates largely discrete supply chains for its stores in each of the UK, US and Europe and the group's food production is largely aligned with the end market.
"As a result there is relatively little group cross-border trading between the UK and the EU. Contingency plans are in place should some of our businesses experience disruption."
