Renewed trade jitters hit FTSE 100; WPP outperforms

London's FTSE 100 slipped on Friday after a report that the United States was delaying a decision on letting its companies do business with Huawei, casting a shadow over global markets, though WPP soared after a quarterly update. Trade worries weighed on Asia-focused HSBC and mining stocks as the FTSE 100 fell 0.2%, but losses were capped by an 8% surge in ad firm WPP after better-than-expected organic sales performance.

A post-earnings jump in gambling firm William Hill and drugmaker Hikma, as well as a rise in shares of security contractor G4S on plans to separate its cash solutions unit, led the FTSE 250 0.3% higher by 0711 GMT.
