Were it not for the Russian invasion, the Ukrainian presidential election would have been held on 31 March. But the country’s parliament, the Verkhovna Rada, decided to postpone it for fairly obvious reasons. Most constitutional experts agreed: Volodymyr Zelensky would remain in power until the inauguration of the next legally elected head of state.
If a presidential term ends while the country is under martial law, the constitution says that the president shall remain in office until a new president can be elected once martial law is suspended, thus ensuring the constancy, stability and continuity of the post.
According to the constitution, the chairman of the Verkhovna Rada takes on the duties of the president should the head of state be unable to complete their term. This applies only if the president resigns, if the president is unable to remain in post for health reasons, if the president is impeached, or if the president dies. In all other cases, presidential power goes on uninterrupted.
