Political experts say there's no heir apparent to Saskatchewan Premier Brad Wall.

Wall has announced he's stepping away from politics after 10 years as premier of the Prairie province.

He says both his province and party will benefit from a fresh perspective.

Charles Smith with the University of Saskatchewan says Wall has become the face of the right-of-centre Saskatchewan Party.

He says possible successors include Energy and Resources Minister Dustin Duncan, Justice Minister Gordon Wyant and Health Minister Jim Reiter.

The University of Regina's Ken Rasmussen says other potential contenders include Finance Minister Kevin Doherty and Tim McMillan, a former provincial cabinet minister who now leads the Canadian Association of Petroleum producers.

Rasmussen says the Saskatchewan Party will have a tough time without Wall and anyone who runs will seem ordinary in comparison.

Wall says he'll remain party leader and MLA for Swift Current until a new leader is chosen.
