Greek officials say the country's new finance minister, Vasilis Rapanos, has been taken to a hospital.

The hospital said Rapanos, 65, was undergoing tests, but did not give a reason. State NET television said that his condition was not serious, but doctors have recommended he remain hospitalized for two or three days. The prime minister's office said an announcement from the hospital was expected shortly.

Rapanos, 65, was to be sworn in to his new post on Friday evening. The rest of the Cabinet of Greece's new three-party coalition government was sworn in Thursday. But the ceremony for Rapanos was delayed so that outgoing Finance Minister Giorgos Zanias could represent Greece at a Eurozone finance ministers' meeting in Luxembourg.
