Investing.com - (LON:London Stock Exchange) fell Monday as its planned €29 bn merger with (DE:Deutsche Boerse) was at risk.
LSE shares were down 3.07% at £3,029.00 at 03:45 ET.
LSE said Sunday the European Commission had requested it sell its stake in its MTS trading platform.
The exchange rejected that request, describing it as "disproportionate."
"The Commission is unlikely to provide clearance for the merger," the LSE said.
