As Glencore eyes Teck, Brad Wall sees echoes of 2010 battle for Potash Corp.

Former Saskatchewan premier Brad Wall says he doesn't know enough of the details to take a public stance on the merits of mining giant Glencore PLC's ongoing hostile takeover bid for Teck Resources Ltd.

But the man who led his province's aggressive campaign to defend Potash Corp. of Saskatchewan against BHP Billiton in 2010 says there are clear similarities between that situation and what's going on now with the battle for Vancouver-based Teck.

He's also confident that in the case of Potash Corp., he and his government were in the right.

"Some things are worth fighting for. Some things are worth saying, 'No, this should be Canadian, this asset should remain Canadian,' " Wall said.
