FACTBOX: Russian president and prime minister: who does what?

(Reuters) - Dmitry Medvedev was sworn in as Russian president on Wednesday but his predecessor Vladimir Putin will serve as his prime minister.

Following is a breakdown of presidential and prime ministerial powers under the current constitutional rules.

Russian officials caution that an exclusively legal view of the division of power does not allow for the deeply personal basis of authority in Russia.

* PRESIDENT:

- Head of state.

- Office in the Kremlin.

- Commander-in-chief of armed forces -- in charge of Russia's nuclear weapons.

- Sets direction of foreign and domestic policies.

- Guarantor of the constitution, citizens' rights.
