Wikipedia says Gordon Bajnai, an entrepreneur aged about 41 at the time, who was in power for just one year, by choice:

> In his first speech as PM, he promised drastic measures to stop the negative spiral of the Hungarian economy, and to ease the burden of the international crisis. He also stated that he would remain in power until he had the solid majority of Parliament behind his austerity package, but will stay no longer than a year.

> The new cabinet formed on 29 May 2010. Bajnai was succeeded by Viktor Orbán. After that he retired from politics and returned to business life.
