FTSE 100 closes lower as GKN drags down index from record highs
Shares in GKN weighed on the UK market after the engineering firm issued a profit warning.
GKN fell nearly 10% after it said full-year profits would be only slightly higher than last year.
It blamed "operational challenges" in its North American aerospace business and a £40m charge resulting from "two significant external claims".
GKN was the biggest faller on the FTSE 100, which closed down 20.80 points, or 0.28%, at 7,535.44.
On Thursday the index hit a record high.
On the FTSE 250, shares in Provident Financial jumped 12.8% after the troubled lender said it had put a recovery plan in place for its home credit business.
In August, shares in the company had dropped by two-thirds in one day after it issued a profit warning. Provident ran into trouble after an attempt to reorganise its door-to-door lending business failed to work.
On the currency markets, the pound was up 0.3% against the dollar at $1.3305 and 0.3% higher against the euro at €1.1240.
