The London Stock Exchange and Germany’s Deutsche Börse have reportedly held talks about buying Poland’s stock market, as tumbling trading volumes in Western Europe encourage exchanges to look for growth in new areas.

Deutsche Börse has been in talks with the Polish government for 18 months about buying its 99% stake in the Warsaw Stock Exchange, Reuters reports. Treasury minister Aleksander Grad named the London Stock Exchange as another likely suitor, according to local newspaper Parkiet.
