Saskatchewan Party Leader Brad Wall is being dogged on the campaign trail by questions about a land deal for the new Regina highway bypass.

The premier says he would like an independent appraisal that was used as the basis for the land sale to be made public, so that people can see that the deal was good.

The Global Transportation Hub, a Crown corporation, bought 204 acres of land west of Regina for $103,000 an acre.

That was more than three times the Highways Ministry's appraised value and far higher than what other landowners in the area got under threat of expropriation.

Wall says the independent appraisal can't be made public without the permission of the seller and the appraiser, but he's urging the Crown corporation to make it happen.

A former landowner has filed a lawsuit that claims the Ministry of Highways misrepresented the value of the land.
