Developer George Wimpey reports that trading in the U.S. market, which accounts for nearly 30% of group sales, has now become difficult, with the forward order book falling 14% in value, according to Reuters.

"In the U.S., market conditions in Florida, California and Phoenix, which are our key markets, have continued to slow, affected by higher interest rates and a strong supply side in new and second hand homes, mainly new homes," said Wimpey Chief Executive Pete Redfern.
