The London Stock Exchange was flanked by both its long-term advisers and newcomers in its acquisition of a majority stake of LCH.Clearnet, in a deal that was “up there in terms of complexity", according to the LSE Group’s chief executive Xavier Rolet.

The UK exchange said this morning it will acquire up to 60% of clearing firm LCH.Clearnet for €463m, in a deal which strengthens the LSE's post-trade business.
