The Plato Partnership, a not-for-profit trading consortium backed by some of Europe's largest investors and investment banks, is to take a leading role in managing dark pools run by the London Stock Exchange's Turquoise equities platform.

These are the first concrete plans laid out by the Plato consortium, which counts Fidelity International, BlackRock, Goldman Sachs and UBS among its members, since news of its formation came to light in December 2014.
