WPP gains fail to lift FTSE 100
(Close): A strong performance from shares in advertising giant WPP failed to lift London's main share index.
The FTSE 100 closed 0.6% lower at 6,954.
Shares in clothing retailers were coming under pressure, with Next shares down 3% ahead of its trading statement later this week.
WPP was the biggest riser on the FTSE 100, up 4.3%, despite seeing UK sales growth slow, which it said could be "the first signs of Brexit anxiety".
However, revenues at the company were boosted by the weaker pound.
Overall sales for the July-to-September period went up 23.6% to £3.1bn. But when adjusted to take account of currency moves, the increase was just 7.8%.
