Turquoise, the share trading platform owned by the London Stock Exchange, has become the largest dark pool by shares traded for the first time, as it takes advantage of the criticism being levelled at rivals.

The LSE's multi-lateral trading facility matched anonymous trades worth €1.7bn (€2.05bn) for the first 10 days of this month, giving it a 26% share of the European MTF dark pool market, according to Thomson Reuters.
