LONDON, March 26 (Reuters) - British fashion and homewares retailer Next Plc (NXT.L) sees sales and margins falling further in 2009, it said on Thursday as it posted an expected 13.9 percent profit decline for the past year.

"It's going to be difficult but it's not going to be the end of the world," Chief Executive Simon Wolfson told Reuters, adding he was confident the group will meet profit expectations in the year to the end of January 2010.

"We're very comfortable with the positioning of our ranges at the moment," he said.

Wolfson said Next has several advantages to enable it to trade through the economic downturn, namely a proven business model, modest debt, a strong internet presence and the ability to take advantage of a weakening property market.

Shares in Next, which have risen 19 percent in the last three months, were down 0.62 percent at 1286 pence at 1030 GMT, valuing the business at 2.52 billion pounds ($3.68 billion).

"We expect Next to emerge as one of the winners from the recession, as capacity drops out of the market and it benefits from strong operational gearing," Panmure Gordon analyst Philip Dorgan said in a research note.

The group said it was budgeting for like-for-like sales to fall between 6 percent and 9 percent at its Next Retail stores chain in its first half to the end of July, with operating margins falling by around 3 percent to about 10 percent.

At the catalogue and online business Next Directory it forecast sales would be flat to down 2 percent, with operating margins broadly flat at around 19 percent.
