Retailer Marks & Spencer shrugged of concerns that poor weather and interest rate rises would affect trading by reporting a rise in first quarter sales.

The group posted a surprise sales growth of two per cent for the three months to June 30.

However, while the high street company's figures were better than expected, the sales growth was the worst recorded for six quarters as M&S battled against wet weather conditions and uncertainty over consumer spending after five rate rises in less than a year.
