REGINA -- Saskatchewan deputy premier Don McMorris has resigned from cabinet after he says he was charged with impaired driving.

McMorris says in a statement that he spoke with Premier Brad Wall, and that Wall has accepted his resignation.

McMorris says he will also leave the Saskatchewan Party's caucus while he deals with the legal aspects of the matter and seeks counselling.

McMorris says in the statement that he has "no words to describe" how sorry he is to his family, colleagues and the people of Saskatchewan.

He says he has indicated many times that drinking and driving is dangerous and unacceptable, which is why the government has strengthened laws and penalties to combat it.

McMorris's statement says he "never should have gotten behind the wheel after drinking," and that he knows better.
