LONDON - Marks & Spencer, Britain's No. 1 clothing retailer by sales, has no plans to change its trading update schedule in light of an unscheduled update on Tuesday from rival Next.

A spokesman for M&S said the firm was sticking to its published announcements timetable, with second quarter sales and first-half results due to be published on Nov. 5.

Next said on Tuesday it may have to cut its profit guidance if Britain's unusually warm autumn weather continues.
