MILAN, Sept 13 (Reuters) - The UK's top share index was weighed down on Thursday by a stronger pound, while retailers fell as a strong update from supermarket group Morrisons MRW.L failed to dispel competition worries.

Morrisons fell 2.1 percent despite its first-half profit growth beating forecasts and a quarterly sales performance that was its best in nine years. analysts were concerned about pressure from low-cost competitors, arguing the strong update was a one-off.

Further pressure on margins seems inevitable," said Neil Wilson, analyst at Markets.com.
