Stock markets in Paris and Frankfurt opened in negative territory today and are headed for weekly losses amid economic and political concerns affecting many sectors in recent days.

The London Stock Exchange was hit by a technical problem today that affected its platform for transmitting market information, delaying the appearance of a change in the FTSE100 index.

“The RNS intelligence service is currently experiencing a global technical problem caused by a third party that does not allow information to be released,” according to a statement on the exchange’s website. “Technical support teams are working to restore service. Other services of the group, in particular the London Stock Exchange, continue to operate as normal.”

The FTSE100 index showed no change at 10:00 Greek time, the opening time of the session on the London stock exchange, while about 20 minutes later it appeared to fall by 0.61%.

In the first minutes of the session, the CAC 40 index in Paris fell 0.27% and the Dax index in Frankfurt fell 0.46%. The management company of the German stock exchange announced that the Xetra trading system began to operate normally this morning, while the Swiss stock exchange group also announced that its systems are operating normally.
