Vienna  - Polish regional politician Marek Nawara remained in critical condition Sunday after suffering severe head injuries while skiing in Austria, according to a spokeswoman at his hospital in the Austrian town of Klagenfurt.

"It's impossible to make any prediction at this stage," spokeswoman Nathalie Wurzer said when asked about Nawara's chances of regaining full health.

The premier of the Malopolska province was skiing in Sankt Margarethen in the province of Salzburg on Friday when he fell and hit his head on the piste surface.

Nawara, 52, suffered severe head and brain injuries and is in an induced coma.

"He is a very good skier," his spokesman Rafal Kocot said from Krakow. "He went skiing year after year."

Kocot said that Nawara's family was also in Austria, and that the premier would receive a computed tomography (CT) scan on Monday.

Police said that although there were no witnesses, they assumed that no one else was involved in the accident. Nawara had not been wearing a helmet.

Another politician involved in an Austrian skiing accident, the premier of the German state of Thuringia Dieter Althaus, is currently recuperating from a head injury he suffered when he collided with a woman on New Year's Day. The Slovakian woman died. dpa
