Chief executive Mike Davies said: “We expect to be able to continue to improve our performance in the second half, which is historically loss-making.”

But trading was dented by the administration of the Birthdays greeting card chain last May, which was a franchise partner of the group. Thorntons lost 94 stores as a result, with franchise sales down 17 per cent to £8.2m.
