Waterford Wedgwood says its trading troubles had worsened after losses more than tripled last year.

The Dublin-based group, which said last month it was cutting 615 jobs in the UK, said the business had suffered major challenges amid falling demand and the impact of the weak US dollar.

Pretax losses widened to £99.1 million in the year to March 31 from a deficit of £29.8 million last time.

Waterford revealed a further slowing in recent trading, saying same-store sales were likely to be eight per cent lower in its first quarter - compared with a decline of six per cent over the year.

Total sales of £486 million were down 12 per cent in the year to March 31, compared with the same period in 2004.

Chief executive Redmond O'Donoghue said: "The year just ended presented serious challenges to our group - a soft dollar, weak demand and below optimal throughput for our manufacturing operations."

He said everybody was "greatly disappointed' by the figures showing operating losses of £54.6 million compared with profits of £18.9 million last time.

However, Waterford said its order books were strengthening, with substantial contracts won in recent weeks and due for delivery in the second half.

"Despite the fact that uncertainties remain, an improved sales trend is anticipated for the second half," the group added.

"Additionally, our new product and marketing programmes are gaining momentum. therefore, despite the fact that uncertainties remain, an improved sales trend is anticipated for the second half."

It was also encouraged by a recent strengthening of the US dollar, which accounts for 40 per cent of its sales.

Waterford, which acquired rival Royal Doulton in January, has seen its industry shrink dramatically in response to falling demand and the impact of low cost competition, mainly from Asia.

Last month's job cuts announcement was part of a restructuring it said would help safeguard the company.

A total of 1,800 jobs were going globally and the closure of the firm's world-famous crystal plant in Dungarvan, Ireland.

A spokesman for Waterford said around 150 positions had "gone or would go" in the Stoke area.

Around 500 jobs were lost before Wedgwood took over Royal Doulton, while around 200 jobs, mainly agency, retail and warehouse positions would be lost in the next two years around the world.

He added the Stoke works remained crucial to Waterford and 2,000 jobs remained.
