Slaughter and May, Jones Day and Cleary Gottlieb Steen & Hamilton have secured lead roles on BHP Billiton’s $40bn (£25.6bn) hostile bid for the Potash Corporation of Saskatchewan, writes the Am Law Daily.

Potash rejected the mining giant’s unsolicited offer on Tuesday (17 August), with BHP today (18 August) confirming a hostile bid at $130 (£83) a share for the Canadian-based company, which is the world’s largest producer of fertiliser.
