Retail boss Sir Philip Green described trading as "competitive and unpredictable" yesterday after sales at his Bhs chain fell 4% in the past six weeks.

The update came as Sir Philip reported a 39.6% fall in Bhs's operating profits to £30.2m for the year to March 29.

He denied himself a Bhs dividend payout for the fourth year in a row.

Sir Philip famously paid himself a £1.2bn dividend from his Arcadia clothing empire, which included shops from Topshop to Burton, in 2005.

Bhs's sales for the full year were 1.4% lower at £860.3m, with like-for-like sales down 2.9%.

Sir Philip said the group achieved a "solid performance in an exceptionally challenging market", adding that the results had enabled Bhs to invest £50m in capital spending in the last financial year.

It has completed the refurbishment of a further 14 stores since the start of the new financial year, with results from those stores showing sales 9% above the rest of the chain. Bhs has now refurbished 33 sites, including its flagship store on London's Oxford Street.

Sir Philip added: "On a domestic front, the market remains competitive and unpredictable. The last six weeks have seen sales down 4%, reflecting not only the market but also the continued impact of the erratic weather patterns. However, I have been very pleased with the performance of some of our product categories."

Childrenswear ranges were up by 5% while Bhs home products outperformed the market with sales growth of 6%, Sir Philip said.

Internationally, Bhs has 15 franchise partners operating out of 93 stores in 16 countries.
