A minister-president (German: Ministerpräsident) is the head of government in a number of European countries or subnational governments, who presides over the council of ministers. The title is similar to Prime Minister, First Minister, and President of the Council.
The German word means "president of the ministers", therefor "Ministers' President" would be a more accurate translation.
Each year one of the ministers-president, or one of the senior Mayors of the city states of Berlin, Hamburg and Bremen, is the President of the Bundesrat. Because Germany does not have a vice president, The President of the Bundesrat will act as the Federal President if the Federal President dies or is out of the country.
