Exchanges in Moscow have clawed back their lead in Russian equity trading over the London Stock Exchange after scores of suspensions and closures since last September sparked an investor exodus.

Investors turned to trading Russian global depositary receipts in London after the Micex and RTS exchanges were both suspended more than 30 times since September last year. Erratic trading patterns triggered shutdowns brought on by Russia's war with Georgia, a banking crisis and investor scandals at miners Mechel and Uralkali.
