Liquidnet, the dark pool that specialises in block trades for fund managers, is considering rolling out its commission payment product in Europe amid a renewed row over how the cost of services are bundled together by brokers.

John Kelly, chief operating officer of Liquidnet, said: "We are in the process of expanding the commission management service and looking at launching in the UK. We are approaching a golden age for buyside head traders in their ability to capture return and this helps them achieve best execution and eases their workflow."
