LONDON -- The London Stock Exchange resumed trading Friday after a "services issue" delayed regular activity on its biggest indexes.
Trading in companies on the exchange's FTSE 100 and FTSE 250 indexes was due to open at 8 a.m. on Friday. It re-opened an hour and 40 minutes late.
Smaller companies were trading as normal.
The last time there was a significant delay to the opening of the exchange was in June last year, when it opened an hour later than normal because of a software issue.
