Fashion firm ASOS hailed "another strong Christmas" as it added to the list of online retail winners after posting a 38% hike in sales.

The group rung up retail revenues of £335.7 million in the four months to December 31, with analysts expecting the firm to smash through its £1 billion turnover target by the end of August.

ASOS - targeted at "fashion forward twenty somethings" - said UK sales were particularly robust, beating its performance from a year earlier with growth of 37%, while international revenues lifted 38%.

The group saw the number of active customers grow to 7.9 million at the end of 2013, up 41% year-on-year.

Nick Robertson, chief executive of ASOS, said: "We have enjoyed another strong Christmas and made a good start to the financial year."
