(Reuters) - London Stock Exchange Group
LSE did not disclose the terms of the deals, in a brief statement issued after markets closed.
In 2013 LSE acquired a majority stake in LCH Clearnet by paying 15 euros per share. After the deal, LSE was expected to own up to 57.8 percent of the firm, leaving other LCH shareholders with at most 42.2 percent.

LCH currently dominates clearing of euro-denominated financial instruments but the future location of euro clearing is uncertain following Britain's move to leave the European Union.
The European Commission has proposed that the EU would help supervise clearing houses like LCH in London after Brexit, with forced relocation of clearing to a euro zone rival such as Eurex only a last resort.
LSE said on Wednesday that all shareholders in LCH had been notified of the share sale and that it would in due course confirm its updated shareholding in LCH following the deals.
