Linklaters and Freshfields Bruckhaus Deringer have won lead roles on a proposed merger between commodities trader Glencore and mining giant Xstrata worth around $82bn (£50bn).

Xstrata confirmed it had received an approach from Glencore for an all-share merger of equals in a statement earlier today (2 February), adding that there was no certainty that any offer would be made. The merger would create one of the biggest mining companies in the world.
