Marks & Spencer Q1 sales fall less than expected

British retailer Marks & Spencer reported a smaller-than-expected drop in first-quarter underlying sales as Executive Chairman Stuart Rose insisted he was "not concerned" by a growing row over his succession. The 125-year-old group, which sells clothes, homewares and food from over 600 stores in Britain and about 285 abroad, said it remained cautious although there were positive signs on consumer sentiment.
