London share trading delayed by one hour
Trading in shares on the London stock market was delayed by an hour on Thursday morning.
A spokesperson for the London Stock Exchange said the opening auction had been held up because of an issue with pricing data.
The LSE would not comment on the nature of the issue or whether it is concerned about an outside breach of its systems.
Trading normally begins at 08:00 each weekday, but Thursday's opening session did not begin until 09:00.
After the market opened, the benchmark FTSE 100 index initially rose, but then fell back and was in negative territory an hour later.
Other European bourses have also faced issues in recent months.
Last month, Euronext experienced a glitch that caused problems publishing major indices, including the French Cac 40.
Equities and futures trading on Germany's Deutsche Börse was delayed by more than an hour in March, because of "technical issues" with its trading system.
